Loose sediment is converted into consolidated sedimentary rock by
A) cooling and freezing.
B) precipitation and melting.
C) recrystallization and transformation.
D) compaction and cementation.

Question

Quizplus · Accepted Answer

Loose sediment is converted into consolidated sedimentary rock through a combination of compaction and cementation. Compaction occurs when the weight of overlying sediment compresses the layers below, while cementation involves the precipitation of mineral material that fills in the spaces between grains and binds them together. This process results in the formation of solid, coherent rock from loose sediment.
