Sedimentary rocks cover 75% of the Earth's surface. Four basic processes are involved in the formation of a clastic sedimentary rock: weathering (erosion)caused mainly by friction of waves, transportation where the sediment is carried along by a current, deposition and compaction where the sediment is squashed together to form a rock of this kind. Sedimentary rocks are formed from overburden pressure as particles of sediment are deposited out of air, ice, or water flows carrying the particles in suspension.
An introduction to SEDIMENTARY ROCKS. Sedimentary rocks form from sediment. Sediment is a general term that indicates loose grains (such as the sand at the beach) and chemical precipitates (such as crystals of salt).Sedimentary rocks can be subdivided in three categories: clastic, chemical, and biochemical sedimentary rocks.ediment is a general term that indicates loose grains (such as the sand at the beach) and chemical precipitates (such as crystals of salt).
