Sedimentary rocks are born cool and on the earth's surface, but mostly underwater. Some types of these are clastic sedimentary rocks, which an example of this type of sedimentary rock is sandstone which comes from the sediment in sand. Another type is organic sedimentary rock. An example of this is limestone(carbonate). Also chemical sedimentary rock and the example of this is gypsum. This type of chemical sedimentary rock is formed after calcite. I learned that there isn't just one type of sedimentary rock, which is what I thought before all of the notes and things we have taken.

Sturwold, Kaylee said...

Sedimentary rocks are cool at the earths surface usually found under water. The most common type of sedimentary rocks are clastic sedimentary rocks. Quartz and clay minerals are examples of sedimentary rocks. Sand and mud is carried down. Sand is made of quartz and mud is made of clay minerals.

Peters,Jennifer said...

Oh I didn't see that quartz and clay are also sedimentary rocks! That's cool. It's cool how there are so many types of each rock.

Peters,Jennifer said...

Oops that last post was @ Kaylee:)

ReddingtonDavid said...

They are the second g.reat rock class. They are mostly made underwater. Clastic, organic and chemical are the three types of sedimentary rocks. Clastic is the most common.

Sturwold, Kaylee said...

@jenn I love limestone I didnt know that there was an organic type of sedimentary rock.

Rembold,Abby said...

Sedimentary rocks are born cool on the Earth's surface. One type of sedimentary rock is clastic. Another type is organic. Examples of sedimenatry rocks are clay and quartz.

sedimentary rocks are born cool at the Earth's surface, mostly under water. They usually consist of layers or strata, hence they are also called stratified rocks. A type of sedimantry rock is sandstone! I love sandstone:) Another type of sedimantry rocks is Limestone. Limestone is sedimentary rock formed from the skeletons and shells of ocean organisms that consists chiefly of calcium carbonateare limestone.

Gerdes,Austin said...

Sedimentary rocks are the second great rock class. Whereas igneous rocks are born hot, sedimentary rocks are born cool at the Earth's surface, mostly under water. They usually consist of layers or strata, hence they are also called stratified rocks. Depending on what they're made of.

Gerdes,Austin said...

@jenn

Who would guess it would be exact opposite of igneous rocks

Lamping Ally said...

Sedimentary rocks are made from mud and sand and gravel and clay. They fall into one of three types of rocks.
We can find these rocks underground.
sandstone is a example of sedimentary rocks.

Savard, Samantha said...

Sedimentary rocks are born cool at the earths surface, mostley underwater. There are 3 types of sedimentary rocks which are Clastic, Organic, and Chemical. Some examples of Sedimantary rocks are limestone and flint. Sedimentary rocks come from igneous and metamorphic rocks and form through the processesof weathering and erosion.

@jenn Wow! I didnt know that there was more than one typ eof sedimantry rock untill i learned about it more! Wow! Your are really smart! lol!

Andrew Gibbous McCarthy said...

Sedimentary rocks are born cool and are found mostly under water on earths surface. Quartz is one example of this rock. Other examples of this rock is gypsum. Gypsum is a type of chemical sedientary rock. Limestone is an example of organic sedimentary rocks

Rembold,Abby said...

@ anna

are there only 2 types of sedimentary rock?

Andrew Gibbous McCarthy said...

@ samantha
i thought there was only 2 types

Savard, Samantha said...

@Jenn
I thougth there was only one type of sedimentary rock too which was calstic, but the other 2 I did not know existed were organic and chemical sedimentary rocks.:)

Sedimentary rocks are the second great rock class. Igneous rocks are born hot, sedimentary rocks are born cool at the Earth's surface, mostly under water. The most common set of sedimentary rocks consist of the regular materials that occur in sediment like mud, sand, gravel and clay. Sediment usually has quartz and clay in it.
We see it in limestone and sandstone.

Lamping Ally said...

@ david
i think its cool that most of the rocks are formed underwater!

Luke said...

Sedimentary rocks cool in layers, usually at the bottom of the sea. There are three types of sedimentary rocks:clastic,organic,and chemical. Once again, you find most sedimentary rocks at the bottom of the ocean.

Mauricio,Courtney said...

They are made on the Earth's surface, and most of the time under water.
There are 3; Clastic, Organic, and chemical.
Clastic; limestone, siltstone, and Red Chert
Organic;Peat, Coal, Petrolium
Chemical; Gypsum, Rock Salt, Dolomites

@Ally and David
I know! I think thats cool too!

Mauricio,Courtney said...

@ Jennifer
Were you able to find where the examples are from?

Tyler said...

Sedimentary rocks form on the earths surface mostly underwater. Sedimentary rocks are also the ones with several layers.Mud, sand and gravel, clay are sedimentary rocks. You can find sedimentary rocks in rivers, oceans and lakes

Schirmer,Brandon said...

Sediment mostly consists of surface minerals — quartz and clays — that are made by the physical breakdown and chemical alteration of rocks.some examples are sandstone and shale.

I agree too i think sedimentary rocks are cool too.

Kresser Jacob said...

Sedimentary rocks are formed under pressure but are usally found underwater but they are also formed from cool rocks most common are clastic rocks

Luke said...

@ REddington,
i didn't know he process of chemical sedimentary rocks. You know, this is the same process that turned the statue of liberty green.

LaGrangeBonnie said...

Sedimentary rocks are formed at cool temperatures and are usually formed under water. Sedimentary rocks have many layers. There are three types of sedimentary rocks. One of them is Clastic Sedimentary rocks. An example of a clastic sedimentary rock is sand stone. Another type is Chemical Sedimentary rock. An example f Chemical Sedimetnary Rock is calcite. Another type of Sedimentary rock is Organic Sedimentary rock. An example is limestone.

LaGrangeBonnie said...

@ Jenn That is what I thought too-that there is one type of sedimentary rock. I knew there were many different rocks classified into sedimentary rocks but I didn't know they were broken down into types as well.

hutson,cody said...

Sedimentary rocks are born cool. There are three diffrent catigories they can fall in based on what there made of.The catigories are clasts,colgometa, and brecca. THey are foud on the earths surface and under the ocean.

Sydney,Vest said...

Sedimentary rocks are the 2nd great rock class. Where igneous rocks are formed hot, sedimentary rocks are formed cool at the earths surface, under water. They usually consist of layers of strata, they are also called stratified rocks. Depending on what there made of, sedimentary rocks have 3 different catagories, here are the names and some examples- One of these types of rocks are Clastic, an example of Clastic is sandstone. Another type is organic, an example of this is limestone. And the last example is Chemical, an example of this type of rock is gypsum. I learned that sedimentry rocks are very detailed and there are many examples of each rock.

bekah said...

they are born cool and om the earths surface, but they are mostly underwater. some are clastic sedimentary rocks, and a example is sandstone which comes from the sediment in sand.another type is organic sedimentary rock that is limestone.

hutson,cody said...

@Storwold,Kaylee


I thought there were three types of sedimentary rocks.

Sydney,Vest said...

yes, jen, i agree. before us blogging and taking notes i had no idea about any of this. but now i understand how this rocks are formed.

I think that it is cool to.

Henry Minning said...

Sedimentary rock is made when sediments like dead plants build up and then form into rocks. They are mostly formed underwater at the surface of the earth. Examples of sedimentary rocks are sandstone and limestone. The types of sedimentary rocks organic and clastic and chemical.

@ Jenn Peters

I also learned about the types of sedimentary rocks.

sedimentary rocks are born cool. they are the majority of the time underwater. a example of this rock is sandstone. it is sand and mud carried down.

bader,lindsay said...

sedimentary rocks are cool rocks. they are mostly under water but they can be on the earths surface.ther are sand stone,limestone and gypsum. sand stone is made out of sand. gypsum and an example of this is calcite.

Sedimentary rocks are born cool and on the earth's surface, but mostly underwater. Some types the rocks are clastic sedimentary rocks, sandstone which comes from the sediment in sand, organic sedimentary rock or limestone, and chemical sedimentary rock or gypsum rock. This type of chemical sedimentary rock is formed after calcite.what i have learned is the sedimentary rock is a mixed rock.

Julia Greve said...

sediments can be made of many different materials; mud, sand, gravel. sedimentary rocks are usually found underwater. some examples of sedimentary rocks are sand stone, which is sand formed tother. and lime, which really comes from another type of sdiment rock called organic sedimentary.

bader,lindsay said...

jenifer i agree with you there our many types of rocks

Alana Gulley said...

Sedimentary rocks are, rocks that are made up of earth materials such as sand, small pebbles, and ect. sedimentary rocks are formed under pressure.and example of sedimentary rock is sand stone, sand stone comes from the sediment in sand.

Where do they come from:They are born cool at the Earth's surface, mostly under water. They usually consist of layers or another way of saying it strata, hence they are also called stratified rocks.

what types are there:Clastic, Organic, Chemical.

what are some examples and where do we find them:Sandstone and we find them in the lower canyons where rivers used to be.

@sydney
I agree with u because we have the same thing for the 3 types of sedimentary rocks.

walter burkart said...

sedimentary rock is made when its already cool mostly underwater in layers mud and sand and gravel and clay are the materials that form it normaly sand becomes sandstone and clay becomes shale examples quartz clay

alyssa weber said...

ALYSSA AND KYLE @ally
do you know what the three types are if not they are Chemical, Clastic, and Organic.

Zach "Hillshire" Viox said...

@ johnson, allison
I did not know organic meant built and formed in the sea. I think thats real cool.

@ Jennifer Peters

I used to think that there was only one type of sedimentary rock to. But then we learned there was more than one.

Sedimentry rocks come from the Earth's surface mostly under water.
EX: limestone. Limestone is created in the ocean.

Sedimentary rocks our formed under intense pressure there for are usually found under water [or were water used to be]. There is Clastic, Chemical and Organic.
Organic sedimentary rocks our formed from dead use to be living things. Plankton etc. that is smashed intill it is a rock.

@ monni szary i never knew quartz and clay could be sedimentary.

John Dinger said...

they come from granular materials like mud and sand. there are clastic, chemical, and organic types of sedimentary rock. some examples are limestone coal and gypsum. they are usally found under the ocean.

@ andrew ehrman
if they are usally found under the ocean why are so many on the surface? if you know please tell me.

Clastic Sedimentary Rocks:
The most common set of sedimentary rocks consist of the granular materials that occur in sediment: mud and sand and gravel and clay.
Organic Sedimentary Rocks:
Another type of sediment actually forms in the sea as microscopic organisms — plankton — build shells out of dissolved calcium carbonate or silica. I also learned that there is more than one type of sedimentary rock.

Calderon, Heidi said...

Sedimentary rocks are born cool from the earths surface, most are under water.
Ex: sedimentary rock is sandstone which comes from the sediment in sand.
surface minerals consist of quartz and clays — that are made by the physical breakdown and chemical alteration of rocks.
Sediment is cemented into rock like sand becomes sandstone and clay becomes shale.

Calderon, Heidi said...

@ anthony,
i agree with what you say about the sedimentary rock and that strata word is a llittle weird to say ha. it sounds very weird to me.

dacoda said...

sedimentary rocks start cool and they are on the earths surface but they are manely under water thes are somtimes calstic rocks and and an example of this is sand stone.

Thorp,Jayden said...

They are the second class. And they are born cool usally in the ocean. They are made of layers of diffrent types of rocks. There many types of sedimentary rock. Sience they are made of diffrent subtances. You could find One in your back yard.

Thorp,Jayden said...

@ Dacoda
I had no clue of that I didn't even know that there was rock named that is cool.

gaddis,breanna said...

the different types of sedimentary rocks are-clastic,organic,and chemical.

clastic-consists of mud,sand,gravel and clay
they are made by the physical breakdown and chemical alteration of rocks.As the sediments are steadily buried over geologic time, they get packed together under pressure and low heat, not much more than 100°C.

organic- organic rocks are forms in the sea as plankton. plankton build shells out of dissolved calcium carbonate or silica. Dead plankton steadily shower their small shells onto the seafloor, where they accumulate in thick layers. That material turns to two more rock types, limestone and chert.

chemical- The same ancient shallow seas sometimes allowed large areas to become isolated and begin drying up. In that setting, as the seawater grows more concentrated, minerals begin to precipitate, starting with calcite, then gypsum, then halite. The resulting rocks are certain limestones or dolomites, gypsum rock, and rock salt respectively. These rocks, called the evaporite sequence, are also part of the sedimentary chain.

Chert can also form by precipitation. This usually happens below the sediment surface, where different fluids can circulate and interact chemically.

MooreKassidy said...

Sedimentary rocks are born cool at the eaths surface, Mostly underwater.They usually consist of layers or strata which means they are satrified rocks.There are 3 types of sedimentary rocks and they are Clastic, Organic and Chemical. You can mainly find them either underwater or where water washes up onto earths surface.

@ jenifer thats cool that quartz and clay are sedimentary rocks

Dupont, Noah said...

Sedimentary rocks usually come from wet areas, such as oceans, rivers, lakes, seas, etc. Some types are clastic sedimentary rocks, organic, and chemical sedimentary rocks. Some examples are limestone, silica, sandstone, and breccia. We find sedimentary rocks around oceans, seas, lakes, rivers, etc. I didn't learn much else here.

Thorp,Jayden said...

But what I want to know is How are these rocks made in the ocean? I ponder that a lot in this unite. I can understand that rock are made under water but how and it be compacted together?!?!

gaddis,breanna said...

@viox
i didnt know organic meant that either. i always thought it ment just coming natrually from the earth.

wessels,kelsey said...

@ jayden thorp
in didnt know that they were 2nd class rocks until i read this expert on rocks

Guthier Nick said...

Sedimentary rocks are born on the earths surface, but modtly underwater. Types of these are clastic, organic, and chemical. An example of clastic is quartz. An example of organic is limestone. An example of chemical is gypsum.

Schmidt, Dominic said...

They come from water,soil,and mud.
there are crystal,and silver,and gold.

josh parsons-The sedimentary rocks forms cool and under water.clastic is first type and can be found anywhere. organic type can be found where there are oceans. chemical is last type and can be found in seas that have isolated and dried up large areas of the sea.

Jenkins,Tom said...

they come from the water.there are calistic and organic and cheimical sedimentry rocks.qarts is found of waches

Yeah i didnt see that but that is cool that quartz and clay is one hmm diffrent.

Dupont, Noah said...

@Andrew Ehrman
Oh I forgot to add this to my post, your's reminded me! Anyways I found it interesting/weird how dead plankton is squashed and made into rocks. I know it's a fossil but it still interests me.

cirkovic, daniel said...

Sedimentary rocks come mostly from underwater because they are born cool. One type of sedimentary rock is clastic which is made out of mud, sand, gravel, and clay. Another type is organic and that is where dead planton and rock layers over each other. Another type is Chemical which forms from chemical reactions. They are usally found in earth and rocks like the Grand Canyon.

Hannah Graff! said...

Sedimentary rocks come mostly underwater, but some cool on the earths surface. the types of sedmentary rocks are:
*Clastic.
*Chemical.
*Organic.
some examples are:
*Limestopne.
*Bauxite.
*Dolostone.
You can find them sand in mud. by the deltas.

cirkovic, daniel said...

@Peters Jennifer

I also thought that there was only 1 type of sedimentary rock. It is cool to learn that they are different types all made different ways!

Anonymous said...

josh parsons- I agree that the sedimentary are interesting and i look forward to learn more about rocks.

Guthier Nick said...

@Peters, Jennifer
Yeah i know i only thought there was one type for each rock.(sedimentary, igneous and metamorphic)

Reis, Elizabeth said...

Sedimentary rocks mostly are formed underwater.
The types are Clastic, Organic and Chemical.
Some examples are calcite, limestone and gypsum.
Clastic sedimentary rocks are the most popular.

Reis, Elizabeth said...

@Jayden
That's what I am curious about too. I imagine rocks being made from hot lava from volcanoes and such, not under the ocean.

Justin said...

they are the second great rock class, also called strata rocks. there are 3 types of strata rocks...

Clastic-the most common,usually consisted with surface minerals

Organic-made of plankton shells,dead plant materials,and could become coal

Chemical-the result of dried up sea sections where the minerals mass together to create stones

sedimentary rock is usually developed underwater

i thought sedimentary rocks were developed every where because you can find them any where but now i remember that all off this used to be water

Justin said...

@ Jennifer

yeah i didn't think the sedimentary has different classes i thought sedimentary were just rock developed in any type of sediment.

Andrew Ehrman said...

@Dupont,Noah

Which rock do you think is more interesting? I think chemical is because the rock comes from the water it self.

Anonymous said...

sedimentary rocks are made cool and mostly found in clay and on the earths surface but mostly found under water.

sedimentary rocks mostly found under water and or found on the top surface of the earth. one type limestone, carbonate, and sand.

kallmeyer, bridget said...

@Alyssa and kyle. Are you sure there are 3 types of sedimentary rocks I thought that there was 2 and they where Clastic and Nonclastic.

Smith,Courtney said...

Sedimentary rocks are the second great rock class of the world. There are three different types of them. They are organic, chemical, and classic sedimentary rocks. Classics are found in sediment such as mud sand and clay. Examples if this type are quartz and clays. Organic are found on the seafloor where dead plankton shells become compacted together onto sedimentary rock. Examples of the organic type are limestone and chert. The last type is chemical. These also start to for on the seafloor but become isolated and begin to dry up and minerals come out of the solution. The rocks that usually come out are rocksalt and gypsum rock. I learned that there is more than one type of sedimentary rock.

Sedimentary rocks are born cool at the earth's surface, mostly under water. Some of these are clastic rocks which consist of clasts which are minerals of different kinds. You can find them you can find these near river edges and sea shores were the sedioments wash up. Some examples are sandstone, breccia and shale.

Anonymous said...

They are broken down rocks from weathering and erosion. 3 types clastic organic chemical. Examples are limestone, sandstone, gypsum. we find them where erosion happened, like near the shore.

Anonymous said...

@Jennifer Peters
I didn't know that there are more than one type of sedimentary rock either. I thought with all our notes they all form the same and cool the same. That they didn't have different groups. THat is a very intersting fact that I will put to us in my notes.

Taylor's blog spot said...

wow there was alot of reading but i found the right answers, well at least i hope i did...... well one type of sedimentary rock is quartz, some exsamples of sedimentary rocks are like mud, sand, clay and dravel. the places you can find them are at rivers, seas, oceans, typical water areas.

Taylor's blog spot said...

another place they might be found is water parks lol im just kidding but it might there ill look this summer if i remimber

CameronIan said...

Sedimentary rock are formed when river wash parts of rocks down into a river basin. while most of these rocks are formed under water some are formed on land. but it more likely that you'll find them forming undder water.

Schwab,Izzy said...

sedimentary rocks can be found on the earths surface although they are usually made under water. one example of sedimentary rock is limestone, another example is sandstone.i learned therer are plenty of different types of sedimentary rocks.

Joseph Pegg said...

The sedimentary rocks are from the earth's surface. The types of sedimentary rocks are Clastic Sedimentary Rocks, Organic Sedimentary Rocks, and Chemical Sedimentary Rocks. Some of sedimentary rocks are a red chert, shale, limestone, and sandstone. Most of the sedimentary rocks are found undre water.
