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. Sedimentary rocks are made of particles of sediments such as sand and clay, or the skeletons and shells of sea creatures. When layers of loose sediment are buried and pressed down under more layers, the particles slowly cement together and lithify (form rock).he Earth is covered in a layer of solid rock called the crust. Rocks are either SEDIMENTARY, IGNEOUS, or METAMORPHIC. Almost all rocks made of minerals, but different rocks contain different mixtures of minerals. Granite, for example, consists of quartz, feldspar, and mica.
