Introduction
Sedimentary rocks are very interesting and exciting. You will learn all about them if you read this research.

Erosion
Erosion takes place when water, wind, and glaciers break up rock and take away the rock as sediment. Rocks on earth's surface are worn by natural processes called weathering or erosion.

Erosion Continued
Weathering is a way climate breaks rocks. In the desert the extreme heat of the day and the cold in the night makes rocks grow and shrink that weakens the rocks.

Sediments
A sediment is carried in rivers or glaciers blown by wind eventually comes to a stop. It builds to form layers which are also called sediments. Sediments are usually washed away or blown sometimes around. That is the next stage in the journey when sedimentary rocks are formed.

How is sedimentary made
The mud is called sediment and a new rock is called sedimentary. Imagine a river colored in brown and mud is flowing in it. It slowly buries as more comes down from the river. Over millions of years the water is squeezed out and pressure turns the mud into new rock.
Sedimentary is one of that make up the earth.

Dolomite and limestone
Both dolomite and limestone are sedimentary rocks. They are also used to make things like buildings
Dolomite is made from a single mineral. On the other hand limestone is formed in shallow seas. Dolomite can be gray to yellowish gray however limestone is white gray or pink. Dolomite can be up to a mile high unlike limestone is very weak and can easily crumble.
Conclusion
I hope you agree that sedimentary rocks are exciting and interesting rocks. To wrap it all up I hope you learned a lot of things about sedimentary rocks.
