B) cementation
C) dissolution
D) compaction and cementation

Question

Quizplus · Accepted Answer

Sedimentary rocks typically undergo lithification through the dual processes of compaction and cementation. Compaction involves the gradual squeezing of sediments through pressure, which helps to reduce pore spaces and increase density. Cementation, on the other hand, involves the deposition of minerals (such as calcite, silica, or iron oxide) in the pore spaces of the rock, which helps to bind the sediment particles together and create a solid mass. Together, compaction and cementation form the basis of lithification for most sedimentary rocks. Dissolution, on the other hand, involves the breaking down of rock material rather than its formation, and is not a typical process of lithification.
