Detailed explanation-1: -The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones.

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: -Compaction and Cementation Dissolved minerals in the ground water precipitate (crystallize) from water in the pore spaces forming mineral crusts on the sedimentary grains, gradually cementing the sediments, thus forming a rock.

Detailed explanation-4: -Clastic Sedimentary Rocks: If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock. Clastic sedimentary rocks may have particles ranging in size from microscopic clay to huge boulders.

Detailed explanation-5: -A sedimentary rock is a layered rock that is formed from the compaction, cementation, and the recrystallization of sediments. Compaction is the squeezing together of layers of sediment due to the great weight of overlying layers of rock.
