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.
Sediments are the end product of the destruction of preexisting rocks (igneous, metamorphic or sedimentary) on the earth's surface. The two major processes leading to decomposition of rocks are (1) mechanical breakage and (2) chemical dissolution. e.g. coal. Sedimentary rocks are characterized by layering. Layering is produced by physical or chemical changes that occur in their environment of deposition. Layers can be found in sedimentary rocks in a wide variety of scales, from much less than a millimeter to many meters.
