The two important processes involved in lithification of sedimentary rocks are compaction and cementation.
Fresh sediment is usually loose material filled with open spaces or pores filled with air or water. Lithification serves to reduce this pore space and replace it with solid mineral material. The main processes involved in lithification are compaction and cementation.
Compaction compresses the sediment to a smaller volume by packing the sediment particles more tightly, removing water from the pore spaces, or by reducing the pressure at the sediment particle contact points. Cementation involves filling the pore spaces with solid minerals that are either deposited from solution or allow particles of existing sediment to grow into the pores.

The type of plate boundary referred here is defined as an ocean-Continent Convergent Plate Boundary.
<h3>What is an ocean-continent convergent plate boundary?</h3>
An ocean-continent convergent boundary is a limit in which the oceanic plate is forced underneath the continental plate.
This type of boundary occurs when an oceanic lithospheric plate crashes against to a continental plate.
In conclusion, the type of plate boundary here is defined as an ocean-Continent Convergent Plate Boundary.

The river is used as a major source of drinking water for Savannah and Augusta, to cool nuclear power plants in Georgia and South Carolina, and to generate hydroelectric power. Other uses include irrigation for agricultural crops and recreation.
