WebThis occurs when sediments are squeezed together by the weight of layers on top of them. Sedimentary rocks made of cemented, non-organic sediments are called clastic rocks. Those that form from organic remains are called bioclastic rocks, and sedimentary rocks formed by the hardening of chemical precipitates are called chemical sedimentary rocks. WebSedimentary deposition is a continuous process; rivers, lakes, and the ocean deposit sediments nonstop at a fairly constant rate. a. true b. false b. false A clastic rock comprised of sand-sized grains derived from the physical weathering of granite and containing a sizable proportion of feldspar is termed ____________. a.
