Answer:
D. sandbar formation
Step-by-step explanation:
Sandbars are formed as a result of coastal deposition activities.
- A sandbar is a region of sand and gravel in a costal area.
- They might be connected to the shore or completely cut off.
- They typically form when waves pull materials from the shore.
- Larger materials can be pulled during a heavy storm.
A shrinking shoreline, mountain shrinkage and retreating glacier are features of erosion.
