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.
Over geological time, layers of sediment are progressively buried. The particles then become compacted and even stuck together by natural cements. That process, called 'lithification', actually turns the mass of sedimentary particles into sedimentary rocks. Some common examples of sedimentary rocks, are claystones, sandstones, limestones and conglomerates. Sedimentary rocks are distinguished from igneous rocks formed by cooling of magma and metamorphic rocks formed by transformation of rocks under increased pressure and temperature.
