GEOLOGY

Detailed explanation-1: -The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification.

Detailed explanation-2: -cementation, in geology, hardening and welding of clastic sediments (those formed from preexisting rock fragments) by the precipitation of mineral matter in the pore spaces. It is the last stage in the formation of a sedimentary rock.

Detailed explanation-3: -The definition of cementation is a process where sediment is chemically glued together when minerals precipitate from the water they are dissolved in and fill the pore space between compressed sediment.

Detailed explanation-4: -The layers are squeezed together and any water mixed in with the sediments is forced out. This process is called compaction. At the same time the particles of sediment begin to stick to each other-they are cemented together by clay, or by minerals like silica or calcite. This process is called cementation.
