Unit 8.3-Sedimentary Rocks
Clastic
Clastic Sedimentary Rocks are formed when sediments are laid down by wind and water,gravity & ice, and then compacted and cemented.
They contain broken pieces of rocks. These pieces are known as clasts
They may have layers like stacks of pages in a book because the sediments build up one on top of another as they are deposited.
These may contain rock fossils
Chemical

Chemical sedimentary rocks are quite soft.
This helps to distinguish them from much harder igneous rocks
Biogenic

And then cemented together
These sediments are mostly from organisms but they are may be small amounts of sediments from weathered rock
Coal is a type of biogenic rock.
