What is the process of compaction and cementation?

1. Compaction occurs when the overlying sediments’ weight compacts the grains as tightly as possible. 2. Cementation is the process whereby dissolved minerals in the water between the grains crystallize cementing the grains together. What is the process of compaction? happens when sediments are deeply buried, placing them under pressure because of the weight of

What conditions in Earth can cause metamorphic rocks to form?
