How can weathering affect the coastline?

Weathering can wear away rocks and cliffs along the coastline, leading to the formation of caves, arches, and stacks. This process can also contribute to coastal erosion, which can result in the loss of land, changes to beach morphology, and increased vulnerability to storm damage. Additionally, weathering can expose new sediment and minerals that can be transported and deposited along the coastline, influencing the shape and composition of the beach.
