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.
The water is squeezed out from between the pieces of rock and crystals of different salts form. The crystals form a sort of glue that sticks or cements the pieces of rock together. This process is called cementation. These processes eventually make a type of rock called sedimentary rock. It may take millions of years for sedimentary rocks to form.
