Answer:
B. Cementation and compaction
Explanation:
Sediments compact under pressure, then they lose fluids, these fluids cement together and eventually becomes solid rock, this process is known as lithification.
Cementation is when fluids from the loose rocks bind themselves together. If the loosely bound rocks are inorganic, they form and turn to clastic rocks but if it contains organic matter, it is known as bioclastic.
In essence, this destructive phase of sedimentary rock formation is known as cementation and compaction.

Answer: Coastal Recession / Erosion
Explanation:
An Estuary is that part of the river that is semi closed and yet mixes with the sea or ocean.
Research has shown that rivers that have Dams built on them have led to rapid coastal erosion. This is because rivers usually carry sediments of SA and other particles with them but these sediments will instead be trapped by the dam instead of being deposited at the Estuary.
This Coastal erosion is a problem because it leads to serious Environmental problems such as the loss of habitat for some organisms, the loss of Coastal protection, loss of biodiversity as well as the reduction in livelihood of people living in Estuarine environments.
