Answer: Big boulders are found in the headland because deposition is occurring in this area.
Step-by-step explanation:
Erosion can be defined as the loss of top most fertile layer of the soil due to the action of the agents like water and wind. The coastal area is prone to erosion due to high water tides and strong wind currents. Boulder beaches are created due to erosion in the coastal area. The erosion and sedimentation of the bedrock and sediments left on the shore due to upwelling of oceanic water are the common causes of development of boulders.
