DESCRIPTION
About sedimentary rocks how they are formed and some examples of them. Is would be good if you wrote down the words Compaction, Cementation, and the examples to help you more.

Types of Rocks - Sedimentary
All you need to know
Sedimentary rocks are rocks made of small bits stuck together
What are they?
Sedimentary rocks are rocks made of small bits stuck together
The Little bits they are made from are washed down rivers
What are they?
Little bits of stuff(sediments)
River carrying bits
The bits that are washed down have some smaller and some bigger bits in them
What are they?
The bits washed down are different sizes
The bits that are washed down have some smaller and some bigger bits in them
The smaller bits mix with the water and make cement.
What are they?
The bits washed down are different sizes
The bits that are washed down have some smaller and some bigger bits in them
The smaller bits mix with the water and make cement.
This helps the little bits stick together
What are they?
The bits washed down are different sizes
The little bits gather at the bottom of the river making a layer
What are they?
Sediments
River
End of river
Layer of Sediments (Little Bits)
The little bits gather at the bottom of the river making a layer
As time goes by there are lots of different layers made
What are they?
Sediments
River
End of river
Build up of different layers
The layer at the bottom has alot of weight on it.
What are they?
Sediments
River
End of river
Build up of different layersLots of weight on this layer
The layer at the bottom has alot of weight on it.
All the weight presses on the layer making it smaller. The little bits in the layer are pushed closer together
What are they?
Sediments
River
End of river
Build up of different layersLots of weight on this layer
The layer at the bottom has alot of weight on it.
All the weight presses on the layer making it smaller. The little bits in the layer are pushed closer together
This is called compaction
What are they?
Sediments
River
End of river
Build up of different layersLots of weight on this layer
The compaction pushes the little bits together
What are they?
The compaction pushes the little bits together
The cement made by the really small bits, makes the sediments stay squished together
What are they?
The compaction pushes the little bits together
The cement made by the really small bits, makes the sediments stay squished together
This is how sedimentary rocks are made

You need to know some examples of Sedimentary rock
Examples
You need to know some examples of Sedimentary rock
The first kind is called Limestone
Examples
You need to know some examples of Sedimentary rock
The first kind is called Limestone Limestone is made of little bits of shells
Examples
You need to know some examples of Sedimentary rock
The first kind is called Limestone Limestone is made of little bits of shells Sometimes whole shells are caught in them
and make fossils
Examples
The next kind is called Mudstone
Examples
The next kind is called Mudstone Obviously it is made of mud
Examples
The next kind is called Mudstone It is made of mud
The last example is Sandstone It is made from Sand
Examples
So basically Sedimentary rocks are made from small bits stuck together by cement and being squished together.
Summary
So basically Sedimentary rocks are made from small bits stuck together by cement and being squished together.
They can have fossils in them
