Lightning is a bright flash of electricity produced by a thunderstorm.
Lightning is an electric current.Small bits of ice bump into eachother this creates electrical charge. The charges concntrate on anything that sticks up like people or mountains. The charge coming from these points eventually connect and then lightning occurs.
How hot lightning is! (54,000 degrees F)
You can see lighning as a far as 100 miles.
cloud-to-ground lightning is the most dangerous type of lightning.
St. Elmo's Fire appears as a blue or greenish glow above pointed objects on the ground.
count the number of seconds between when you see the lightning and hear the thunder. Take the number of seconds and divide by 5 and that will tell you how far away the storm is in miles.
Keep an eye at the sky. Look for darkening skies, flashes of lightning, or increasing winds. Lightning often proceeds rain, so don’t wait for the rain to begin. If you hear the sound of thunder, go to a safe place immediately.

Lightning is an ton of electric currents inside a cloud made of many small bits of frozen raindrops bump into each other as they move around in the air. All of those collisions create an electric charge. After a while, the cloud fills up with electrical charges. and it releases lightning. lightning kills more people than any other natural diaster 75-100 people.if someone is struck by lightning Call 911 or send for help rite away. The injured person can not carry an electrical charge

The most interesting thing that i read on this site is that lightning is an electric current. Lightning bolts can be seen as much as 100 miles from us, depending on the height of the bolt, the clarity of the air, and our elevation.Cloud-to ground lightning is really dangrouse. Most cloud-to-ground lightning strikes come from the negatively charged bottom of the cloud traveling to the positively charged ground below. Intercloud lightning is when a lightning strike occurs when there are positive and negative charges within different clouds and the strike travels in the air between them. Intercloud is less commen than intracloud. High altitude lightning is a form of lightning appears as brightly colored flashes, high above thunderstorms. St. Elmo's Fire appears as a blue or greenish glow above pointed objects on the ground. It is created when tiny positively charged sparks reach up in response to negatively charges in the air or clouds above the ground. Next time you see a storm, count the number of seconds between when you see the lightning and hear the thunder. Take the number of seconds and divide by 5 and that will tell you how far away the storm is in miles. IF YOU’RE OUTDOORS: Keep an eye at the sky. Look for darkening skies, flashes of lightning, or increasing winds.

some lightning safty tips are if you hear thunder, go to a safe place immediatly- a car, it has rubber tires, shut all windows for safty. if there isnt any shelter, stay away from trees, if your with a group, stay 15ft away from eachother... do these things you will most likely be safe

Wow! i didn't know that lightning is an electric current! (till today!) I hope that i will learn much more about lighnting in the future. Whst do you think?

i learned that positive charges or protons form at the top of the cloud and the negative charges or electrons form at the bottom of the cloud. the charges connects with a charge reaching down from the clouds and - zap - lightning strikes. something interesting is that lightning is approximately 54,000 degrees Fahrenheit. the lightning bolts can be seen as much as 100 miles from us.cloud-to-ground lightning strikes come from the negatively charged bottom of the cloud traveling to the positively charged ground below.
Intercloud lightning is less common. It's when a lightning strike occurs when there are positive and negative charges within different clouds and the strike travels in the air between them.
high alltitude lightning is a form of lightning appears as brightly colored flashes, high above thunderstorms. St. Elmo's Fire appears as a blue or greenish glow above pointed objects on the ground. Next time you see a storm, count the number of seconds between when you see the lightning and hear the thunder. Avoid sheds, picnic areas, baseball dugouts and bleachers. If there is no shelter around you, stay away from trees.

@ DeeAnna (:
I know i agree i can't believ tornados kill more people than hurricanes do! I would have never thought that.

Lightning is a bright flash of electricity produced by a thunderstorm.

Lightning is caused by many small bits of ice (frozen raindrops) bump into each other as they move around in the air. After the collisions is causes and electrical charge, then the cloud fills up with electrical charges, and positive charges form at the top of the cloud and at the bottom of the cloud negative charges form. SInce opposites attract they attract to eachother and that causes lightning.

Within distant thunderstorms, the lightning bolts can be seen as much as 100 miles from us, depending on the height of the bolt, the clarity of the air, and our elevation.

Clooud to ground lightning is the most dangerous type of lightning.
Intercloud lightning is less common. It's when a lightning strike occurs when there are positive and negative charges in different clouds and the strike travels in the air between them.

High altitude lightning is lightning thats appears as brightly colored flashes, high above thunderstorms. You can't see these types of lightning from the ground.

St.Elmos fire appears as a blue or greenish glow above pointed objects on the ground.

You can tell how far away a storm is by using thunder. When you see a storm, count the number of seconds between when you see the lightning and hear the thunder. Take the number of seconds and divide by 5 and that will tell you how far away the storm is in miles.

SOme safety tips are if your outside lightning often proceeds rain, so don’t wait for the rain to begin. and the best place to go is a sturdy building or a car, but make sure the windows in the car and building are shut. If your indoors avoid water. It’s a great conductor of electricity, so do not take a shower, wash your hands, wash dishes or do laundry.

The most interesting thing we read was that lightning kills and injures more people each year than hurricanes or tornadoes; between 75to 100 people.

Lightning is caused when ice crystals(frozen rain drops) collide within a cloud causing an electrical charge. Lighting is an electric current. The most interesting thing I read is lightning is 54,000 degrees farenheit. It's six time's hotter than the surface of the sun!!! Cloud to ground lightning usually comes from clouds where it is negatively charged at the bottom and positively charged at the top. Intercloud lightning is less common and happens when positive and negative charges are in different clouds and the strike travels between them. High altitude lightning has been named other names such as "green elves" or "red sprites" because they are colorful, however since they are up higher than thunderstorms you can't see them from the ground. St. Elmo's Fire appears as a bluish or greenish glow above pointed objects. It happens when tiny positvely charged sparks find negative charges in the clouds or in the air. If there is a storm around where you are you might see St. Elmo's Fire before a lightning strike. To find how far away a storm is you count the number of seconds between the time you see lightning and the time you hear thunder. Then divide the number of seconds by five and thats about how far away from the storm you are. If you are outside try to find a safe place like a car or a building, but if you can't stay away from picnic tables, dugouts, bleachers, etc. Crouch down twice as far away as a tree is tall. Put your hands over your ears. Stay away from water even when your indoors. Also stay away from corded phones, computers, etc.

Lightning is a bright flash of electricity produced by a thunderstorm.

Within a thundercloud way up in the sky, many small bits of ice (frozen raindrops) bump into each other as they move around in the air. All of those collisions create an electric charge. After a while, the whole cloud fills up with electrical charges. The positive charges or protons form at the top of the cloud and the negative charges or electrons form at the bottom of the cloud. Since opposites attract, that causes a positive charge to build up on the ground beneath the cloud. The grounds electrical charge concentrates around anything that sticks up, such as mountains, people, or single trees. The charge coming up from these points eventually connects with a charge reaching down from the clouds and lightning strikes.

The most interesting thing that I learned is that 75 to 100 people die oe get injured.

The lightning bolts can be seen as much as 100 miles from us, depending on the height of the bolt, the clarity of the air, and our elevation.

Cloud-to-ground lightning strikes come from the negatively charged bottom of the cloud traveling to the positively charged ground below.

It's when a lightning strike occurs when there are positive and negative charges within different clouds and the strike travels in the air between them.

This form of lightning appears as brightly colored flashes, high above thunderstorms.

It is created when tiny positively charged sparks reach up in response to negatively charges in the air or clouds above the ground.

@ Anna that's scary that it kills that many people, but did it say like in the U.S or in the world becaus if its 75- 100 people in the world it's really not that many, but its still sad and really scary

Andrew Gibbous McCarthy said...

It is a breif flash of electrical energy that is very dangerous and kills more than hurricanes and tornadoes. It is produced by small clumps of ice that rub together. All of the collisions form a eletrical charge. Lightning can be up to 54,000 degrees fahrenheit. And is a white-yellow color.

Have you ever rubbed your feet across carpet and then touched a metal door handle? If so, then you know that you can get shocked! Lightning works in the same way.

Lightning is approximately 54,000 degrees Fahrenheit. That is six times hotter than the surface of the sun!

If you see dark clouds, then lightning could be present, but the best thing you can do is to listen for thunder.
Within those distant thunderstorms, the lightning bolts can be seen as much as 100 miles from us, depending on the height of the bolt, the clarity of the air, and our elevation. Thunder, in comparison, has a much shorter range of detection - usually less than 15 miles in a quiet rural setting and under 5 miles in a noisy city environment.


All lightning is dangerous, but cloud-to-ground lightning is the most dangerous type of lightning. Most cloud-to-ground lightning strikes come from the negatively charged bottom of the cloud traveling to the positively charged ground below.


What is intercloud lightning?
Intercloud lightning is less common. It's when a lightning strike occurs when there are positive and negative charges within different clouds and the strike travels in the air between them.
High-altitude lightning has been given other names such as "red sprites," "green elves," and "blue jets." This form of lightning appears as brightly colored flashes, high above thunderstorms. You can't see these types of lightning from the ground.

St. Elmo's Fire appears as a blue or greenish glow above pointed objects on the ground. It is created when tiny positively charged sparks reach up in response to negatively charges in the air or clouds above the ground. If a thunderstorm is nearby, St. Elmo's Fire might be seen right before a lightning strike.

Yes, you can use thunder to tell how far away a storm is. Next time you see a storm, count the number of seconds between when you see the lightning and hear the thunder. Take the number of seconds and divide by 5 and that will tell you how far away the storm is in miles. For example: If you counted 10 seconds between the lightning and the thunder, the lightning is 2 miles away!

Lightning Safety Tips
IF YOU’RE OUTDOORS: Keep an eye at the sky. Look for darkening skies, flashes of lightning, or increasing winds. Lightning often proceeds rain, so don’t wait for the rain to begin. If you hear the sound of thunder, go to a safe place immediately.

A lioghtning bolt can be seen as far as 100 miles! But thunder can only be heard from about 15 miles away and in a noisy city only 5 or less!
Cloud to ground lightning is the most dangerous type of lightning!
cloud to ground lightning strikes the tall things like trees and buildings. These lightning bolts can cause fire and property damage.
Lightning is the second weather related kill!
In intercloud is less common. Its when a lightning strike occurs when there are positive and negative charges within different clouds and the strike travels in the air between the them.
High alitude lightning is high altitude lightning has been given other names such as red sprites, green elves, and blue jets. This form of lightning appears as brightly colored flashes, high above thunderstorms. You cant see these types of lightning from the ground.

St.elmos fire is blue and green glow. That is seen right before lightning strikes.
You can tell how far away a strom is when you count how many seconds occur between when you hear thunder and time you see the lightning flash. Then you divide that number by 5 and that total is how many miles away a thunder storm is.
Some lightninmg saftey issues is if your outside if you see lightning and cant get to a safe place get down on your hands and knees and keep your head tucked in. If your insode or outside make sure you get to a safe place immediately.

If there is no shelter around you, stay away from trees. Crouch down in the open area, keeping twice as far away from a tree as far as it is tall. Put your feet together and place your hands over your ears to minimize hearing damage from thunder. If you’re with a group of people stay about 15 feet from each other. Stay out of water, because it’s a great conductor of electricity. So do not take a shower, wash your hands, wash dishes or do laundry Also, don’t stand in puddles and avoid metal. Stay away from clotheslines, fences, and drop your backpacks because they often have metal on them. If you’re playing an outdoor activity, wait at least 30 minutes after the last observed lightning strike or thunder. Do not use a corded telephone. Lightning may strike exterior phone lines. Do not use electric equipment like computers and appliances during a storm. Stay away from windows and doors and stay off porches. IIf someone is struck by lightig call for help. Call 911 or send for help immediately. The injured person does not carry an electrical charge, so it is okay to touch them.

Lighting is produced by a bright flash of electricity prouduced by a thunderstorm. The electricity is created by ice crystals bumping into eachother and that makes an electrical charge. the most interesting thing i think is that lighting is 54,000 degrees farenhite you can see lighting as far as 100 miles away and cloud to ground lighting is when the lighting comes down in bolts and intercloud lighting is when the lighting is flashing in the sky. Cloud to ground is more dangerous and if you hear thunder go inside because just because you dont see the lighting doesnt mean its not coming and with thunder there comes lighting

Lightning is a bright flash of electricity produced by a thunderstorm. Lightning is an electric current. The positive charges or protons form at the top of the cloud and the negative charges or electrons form at the bottom of the cloud. Since opposites attract, that causes a positive charge to build up on the ground beneath the cloud. The grounds electrical charge concentrates around anything that sticks up. The most intersesting part for me was learning how the lightning formed. You can see lightning from 100 miles away. Cloud-to-ground lightning bolts strike the tall objects, like trees and buildings. These lightning strikes can cause fire and property damage. If you're the tallest object, then lighting can strike you. Intracloud lightning is the most common type of lightning. This occurs when there are both positive and negative charges within the same cloud. Usually, the process takes place within the cloud and looks like a bright flash of light which flickers. High-altitude lightning has been given other names such as "red sprites," "green elves," and "blue jets." This form of lightning appears as brightly colored flashes, high above thunderstorms. St. Elmo's Fire appears as a blue or greenish glow above pointed objects on the ground.

Next time you see a storm, count the number of seconds between when you see the lightning and hear the thunder. Take the number of seconds and divide by 5 and that will tell you how far away the storm is in miles. One saftey tip I read was that when your skin feels tingly, you should get down on your knees and cover your head because that means lightnings about to strike.

@ Bonnie LaGrange

I found your saftey tip about what to do if you are outside during a thunderstorm very intersesting.

Lightning is a bright flash of electricity produced by a thunderstorm. All thunderstorms produce lightning and are very dangerous. If you hear the sound of thunder, then you are in danger from lightning. Lightning kills and injures more people each year than hurricanes or tornadoes; between 75 to 100 people.

What causes lightning?
Lightning is an electric current. Within a thundercloud way up in the sky, many small bits of ice (frozen raindrops) bump into each other as they move around in the air. All of those collisions create an electric charge. After a while, the whole cloud fills up with electrical charges. The positive charges or protons form at the top of the cloud and the negative charges or electrons form at the bottom of the cloud. Since opposites attract, that causes a positive charge to build up on the ground beneath the cloud. The grounds electrical charge concentrates around anything that sticks up, such as mountains, people, or single trees. The charge coming up from these points eventually connects with a charge reaching down from the clouds and - zap - lightning strikes!

How far away can you see lightning and hear thunder?
Within those distant thunderstorms, the lightning bolts can be seen as much as 100 miles from us, depending on the height of the bolt, the clarity of the air, and our elevation. Thunder, in comparison, has a much shorter range of detection - usually less than 15 miles in a quiet rural setting and under 5 miles in a noisy city environment.

What is cloud-to-ground lightning?
All lightning is dangerous, but cloud-to-ground lightning is the most dangerous type of lightning. Most cloud-to-ground lightning strikes come from the negatively charged bottom of the cloud traveling to the positively charged ground below.


Cloud-to-ground lightning bolts strike the tall objects, like trees and buildings. These lightning strikes can cause fire and property damage. If you're the tallest object, then lighting can strike you. Lightning is the second weather related killed.

What is intercloud lightning?
Intercloud lightning is less common. It's when a lightning strike occurs when there are positive and negative charges within different clouds and the strike travels in the air between them.Intracloud lightning is the most common type of lightning. This occurs when there are both positive and negative charges within the same cloud. Usually, the process takes place within the cloud and looks like a bright flash of light which flickers.

What is high-altitude lightning?
High-altitude lightning has been given other names such as "red sprites," "green elves," and "blue jets." This form of lightning appears as brightly colored flashes, high above thunderstorms. You can't see these types of lightning from the ground.

I found it interresting that lighting is 54,00 degress F. You can see lighting 100 miles away from where you are standing.Cloud to ground lighting is the most dangerous type of lighting and comes from a negative charged bottom of a cloud traveling to positive ground below. Intercloud-positiv and negative charges within different clouds and the strike travels in the air between them. High altitude lighting- brightly colored flashes high above thunderstorms cant see from the cround. st. elmos fire-accures right befor lighting strickes. You count the second between lighting and thunder accures then divid the second by 5, that is how you can tell how far away a storm is. as soon as you hear thunder or see dark clouds take shelter as soon as possible.

If you hear the sound of thunder, then you are in danger from lightning. Lightning kills and injures more people each year than hurricanes or tornadoes; between 75 to 100 people.Lightning is an electric current. Within a thundercloud way up in the sky, many small bits of ice (frozen raindrops) bump into each other as they move around in the air.
ll of those collisions create an electric charge. After a while, the whole cloud fills up with electrical charges. The positive charges or protons form at the top of the cloud and the negative charges or electrons form at the bottom of the cloud.Since opposites attract, that causes a positive charge to build up on the ground beneath the cloud. The grounds electrical charge concentrates around anything that sticks up, such as mountains, people, or single trees. The charge coming up from these points eventually connects with a charge reaching down from the clouds and lightning strikes!

lighting is a bright flash of electricity caused by thundersotorms. frozasn rain causes it to ocere becsause they rub together and produce lingight.the lighting traker is my fav part.you can see them up to 100 miles away.from negitive cargegd cloud to positivle charged groud is cloud to ground lingting.st elmods fire is a blue or grenisgh glow above pontid objects on the ground. take the nuber of seconds and divide by 5.get in a sterdy car or buliding,avoid water,stay in basment.

Lighting is a flash of electricity made by a thunderstorm. Lighting is made by small bits of ice bump into each other and make elecrical charges until a whole cloud is filled with them, then postitive or negative charges are made. Since opposites attract a psotive charge goesw beneath the cloud. Then lighting is attracted to things like mountains and trees, Then charges from the objects on the ground connect with the charges in clouds and the a lighting strike occurs. The most interesting thing I read about was how lighting formed because I never knew how it formed. You can see lighting uo to 100 miles. Cloud to groundn lighting is lighting that hits the ground. It happens because the negatively cahrged lighting hits the positively chraged ground. Intercloud lighting is when a lighting strike appears when there are positive and negative charges in two different clouds and the lighting goes in between the air inbetween them. High altitude lighting is lighting above thunderstorms which is very bright. St. Elmo's Fire looks like blue or greenish glow above pointed objects. To tell how far away lighting is time the time it takes for you a see lighting and hear thunder. Then divide that number by five. Some lighting safety tips are stay away from water or trees because they can conduct electricity and the best place to go is a sturdy car or building.

Lightning is a bright flash of electricity produced by thunderstorms. It is caused by small droplets of rain, but are really small droplets of ice, collide in the air, high in the clouds. Each time they collide they build of electrical charges (Kind of like static electricity, only far more severe.) After a while the whole cloud fills up with them (Positive charges)while there are negative charges at the bottom of the cloud, since opposites attract there is a positive charge on the ground below. It mostly charges things that are sticking upo from the group (People, trees, etc.) Eventually the charge from the objects standing up hit the charges above and then lightning strikes. The most interesting thing I found is that lightning is 6 times hotter than the surface of the sun! How the heck does that work?
You can see lightning from up too 100 miles away or so. Cloud to ground lightning is the most dangerous and is when the lightning strikes the ground. Intercloud lightning (Not to be confused with intracloud lightning) is when lightning pretty much moves through the clouds. High altitude lightning is not visible from ground but takes place high above the thunderstorm. They're brightly colored flashes. You can tell how far away a storm is by dividing the number of a seconds between the lighting and the thunder, then you get the miles. Some lightning safety tips are to get indoors if you see it, if you can't go to a car, if you can't the crouch in an open field, away from trees and people. Also cover your ears.

I also know St. Elmo's Fire from the book Taken, quite a good book :P

St. Elmo's Fire appears as a blue or greenish glow above pointed objects on the ground.you can tell how far a storm is away by doing,counting the nuber of second afer each lighting strike to you here thunder then you divide by 5 then thats ow many miles the storm is away from you. Saftey tips for remebering lighting is Keep an eye at the sky. Look for darkening skies, flashes of lightning, or increasing winds. Lightning often proceeds rain, so don’t wait for the rain to begin. If you hear the sound of thunder, go to a safe place immediately.

I wonder why you should stay away from baseball dugouts. Maybe because they are partly metal and metal is a conductor of electrcity.

Color of lighnting.
Lightning bolts can be seen as much as 100 miles from us.
All lightning is dangerous, but cloud-to-ground lightning is the most dangerous type of lightning. Most cloud-to-ground lightning strikes come from the negatively charged bottom of the cloud traveling to the positively charged ground below.
Intercloud lightning is when a lightning strike occurs when there are positive and negative charges within different clouds and the strike travels in the air between them.
High-altitude lightning has been given other names such as "red sprites," "green elves," and "blue jets." This form of lightning appears as brightly colored flashes, high above thunderstorms.
St. Elmo's Fire appears as a blue or greenish glow above pointed objects on the ground.
Yes take the number of seconds and divide by 5 and that will tell you how far away the storm is in miles. For example: If you counted 10 seconds between the lightning and the thunder, the lightning is 2miles away!
Avoid sheds, picnic areas, baseball dugouts and bleachers. If there is no shelter around you, stay away from trees.

You can see lightning 100 miles away depending on the height of the bolt,the clairty in the air and elevation.
Cloud-to-ground lightning is the most dangerous type of lightning itslightning strikes come from the negatively charged buttom of the cloud traveling to the positively charged ground below.
Intercloud lightning is less commen it occurs when positive and negitive charges within different clouds.High altitude lightning is brightly colored flashes high above thunderstorms.

Once there are enough collisions there is eventually a lightning strike. The most interesting thing I saw was that lightning kills between 75 to 100 people a year! the farthest we can see lightning is 100 miles. Cloud to ground lightning is the most dangerous type of lightning and come from the grounds electric charge. Intercloud lightning is lightning with charges from 2 different clouds and the strike is between them. High altitude lightning is lightning that strikes as bright colors.St. Elmos fire is created when tiny positively charged sparks reach up in response to negatively charges in the air or clouds above the ground. You can count the number of seconds between when you see the lightning and hear the thunder. Take the number of seconds and divide by 5 and that will tell you how far away the storm is in miles. Look for darkening skies, flashes of lightning, and increasing speeds.

I agree with you and anna i didnt know that lightning was a electric current.

@Lamping Ally,
I didn't ever think lightning would ever be 54,000 degrees! Thats crazy!

I didn't know trees attracted lightning?

bright flash of electricity produced by thunderstorms is lightning. Its caused by bits of ice moving in thunderstorms that bump into each other causing electric charges. The most interesting fact was the lightning is 6 times hotter than the suns surface. If you counted 10 seconds between lightning and thunder it is 2 miles(10/5=2)It is lightning that is most dangerous and Come from negative charge going to positive charge. Inter cloud lightning is when negative and positive strike through the air through different clouds. Altitude lightning is High colored flashes above the thunder storms.

Lighting is a bright flash of electricty,produced by a thunderstorm.tiny slivers of ice bump into eachother this creates an electrical charge. The charges. the most intresting thing i learned is lighting is 54,000 degrees F. you can see lighting from far away as 100 miles about. cloud to ground lighting is the worst kind most dangerous one.St. Elmo's Fire appears as a blue or green glow, above pointed objects on the ground.
count the number of seconds between when you actually see the lighting and hear the thunder. then divide by 5 to see how far away u actually are. Lighting is very common byr should be watched with a close eye. when lighting is really bad its best to go to your basemen for safety.

lightening is a discharge of energy produced by a thundercloud. water droplets collide at the top of cloud, creating a charge. This charge is different than that of the bottom of the cloud, and the energy moves towards its opposite. if a tree is oppositely charge the lightening may hit the tree. Cloud-ground is when lightening strikes something on the ground. intercloud lightening is when a cloud is oppositely charged and so the lightening strikes the cloud. High altitude lightening is above the storm cloud, and cant be seen with the naked eye. st elmos fire is green or yellow lighting appearing above pointed objects. some tips are to stay indoors, away from trees.

@ taylor,
i didnt know that you should be 15 feet away, but thats innteresting. i knew you were supposed to stay in the car though. the most interesting thing i learned was how a cloud is charged.

Lighting is a very bright flash of electricity produced by a strong thunderstorm.
Lightning is an electric current occured by bits of ice bumpped into eachother which then creates eletrical charge. The charge connects to anytthing that stickls up. (poeple). Then lightning occurs. Lightning attracts to the oppisite force.
Lighting is very very very hot. around 54,000 degrees farentheit. You can see lighting strike from around 100 miles away. Cloud to ground lightning is the most dangerous type.
sst. Elmos fire appears as a blue or green glow, pointed objects on the ground.
if you count the number of seconds between when you see the lightning and hear the thunder, then take the number of seconds and divide by five and that will tell you how far away the storm is in miles.
Keep an eye at the sky, keep an eye out and look for darkening skies, flashes of lightning, or increasing winds. Lightning often proceeds rain, so don’t wait for the rain to begin. If you hear the sound of thunder, go to a safe place immediately.

lightning is an electrical current many small bits of ice collide and cause an electrical charge

if you see dark clouds lightning could be present.

you can see lightning from 100 miles away

cloud-to-ground lightning is the most dangerous type of lightning.Most cloud to ground lightning strikes come from the negatively charged bottom of the cloud traveling to the positively charged ground below.

Intracloud lightning is the most common type of lightning.
This occurs when there are both positive and negative charges within the same cloud.

High-altitude lightning has been given other names such as "red sprites," "green elves," and "blue jets." This form of lightning appears as brightly colored flashes, high above thunderstorms.

st. elmosfire is a greenish yellow above pointed objects on the ground it is created by tiny positivly charged sparks reach up in response to negatively charges in the air or clouds above the ground.

to tell how far away a storm is you count when you see a lightning strike you count untill you hear the thunder

you should stay away from baseball dougouts because the metal baseball bats or other metal items could attract lightning

lightening- bright flash of electricity produced from a thunderstorm.
lightning is caused when small bits of ice bump into each other, causing an electrical charge to form. after a while, electricity builds up, and is released with the negative charges combining with the positive charges of the ground below.

we can usually see lightning up to 100 miles away depending on the high of the bolt and the severeness of the storm.

cloud to ground lightning strikes comes from the negative charged part of the cloud traveling to the positive charged ground below- creating the most dangerous trype of lightning.

intercloud is when there are negative and positive charges in the cloud. the most common type of lightning (who knew there were types?) produces flicks of the electricial charges.

the human body can sort of sense when lightning is about to strike. when your hair stands on end, this means to get indoors or in a car, because its coming.
safety tips:
1. get inside a building
2. or get inside a car
3.when you hear lightning and can't get to somewhere safe, curl up,do not lay
flat.
st elmo's fire is when a breif flash of the color blue or green appears over striked objects, occuring when positive charged sparks go up in response to negative charges in the air.

It was really cool that lightning is hotter than the sun! We grow up hearing that the sun is soooo hot and all this time lightning is hotter!

@ Alyssa

Yeah, it's because of the rubber tires that kind of like deflect the lightning I guess it's something like that.
