Sediment is eroded material deposited on the Earth by water, ice, or air.[1] Sediments are found in a wider variety of settings: from desert dunes, river deltas, mountain ranges, and even the deep sea floor.[2] After enough grains have accumulated in the depositional environment, one of two different processes may occur and cause the formation of Sedimentary Rock. Either compressional forces will bond the sediment grains together, or other minerals may bond the grains together by precipitating between them from water sources flowing through the sedimentary environment.
