GEOLOGY

Detailed explanation-1: -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-2: -Compaction is the process by which overlying pressure from rocks and soil reduces the size or volume of sediments. Cementation is the process of binding and hardening sediments into hard rock.

Detailed explanation-3: -Finally, lithification is the process by which clay, sand, and other sediments on the bottom of the ocean or other bodies of water are slowly compacted into rocks from the weight of overlying sediments.

Detailed explanation-4: -Compaction is the process of squishing air or water from between particles of sediment. Cementation is the process of minerals sticking individual grains of sediment together.

Detailed explanation-5: -lithification (lithify) Processes that turn loose sediment into hard rock. This happens by compaction (when sediments are buried by newer sediment and squeezed together) and cementation (when minerals crystallize in pores and hold sediments together).
