A sedimentary rock is a layered rock that is formed from the compaction, cementation, and the recrystallization of sediments. Compaction is the squeezing together of layers of sediment due to the great weight of overlying layers of rock.
Sedimentary rocks are formed by sediment that is deposited over time, usually as layers at the bottom of lakes and oceans. This sediment can include minerals, small pieces of plants and other organic matter. The sediment is compressed over a long period of time before consolidating into solid layers of rock. Sedimentary rocks forms layers called strata which can often be seen in exposed cliffs.
