They're called clastic sedimentary rocks.
Sedimentary rocks form as pieces of loose material get pressed or cemented together. The process of forming sedimentary rocks is lithification.
When older rocks, plants, and other loose material get pressed or cemented together
If they are deposited, compacted, and cemented together, they form a sedimentary rock.
Sedimentary rocks are made by the majority of the crust are covered by a thin veneer of loose sediment, and the rock which is made as layers of this debris get compacted and cemented together.
If you press together pieces of rock and organic materials, fossils will form. However, this process takes several years to hundreds of year to complete.
Loose rock material is called detritus.
