Specific to layered sedimentary rocks, geologists long ago determined that studying such layers -- what is called the âsuperpositionâ of the rocks -- is the key to tracking the Earthâs evolution, including the ebb and flow of oceans, lakes and rivers, and the shifting of sands and other forms of sediment.
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.
