GEOLOGY

Detailed explanation-1: -happens when sediments are deeply buried, placing them under pressure because of the weight of overlying layers. This squashes the grains together more tightly.

Detailed explanation-2: -compaction-The process that presses sediments together. Over millions of years, thick layers of sediment build up. These heavy layers press down on the layers beneath them.

Detailed explanation-3: -Compaction occurs after the sediments have been deposited. The weight of the sediments squeezes the particles together. As more and more sediments are deposited the weight on the sediments below increases. Waterborne sediments become so tightly squeezed together that most of the water is pushed out.

Detailed explanation-4: -Compaction and cementation are important stages in the sedimentary rock cycle. The sedimentary rock cycle describes how sedimentary rock forms and happens in the following order: erosion, deposition, compaction, cementation.

Detailed explanation-5: -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.
