Sea arches and sea stacks provide evidence of weathering and erosion. In three to five sentences, explain the roles weathering and erosion play in creating these landforms and how deposition is involved in shaping the shorelines.(4 points)

Weathering is the process of breaking down rocks into smaller fragments through physical, chemical, and biological processes. This weakens the rocks and makes them more susceptible to erosion. Erosion is the transportation of those weathered rock fragments by natural agents such as wind, water, and ice. As these agents erode the coastline, they carve out sea arches and sea stacks by wearing away softer rock layers and leaving behind more resistant rock layers. Deposition occurs when eroded materials are dropped or deposited in a new location. It plays a role in shaping shorelines by forming beaches, dunes, and barrier islands, which contribute to the overall coastal landscape.
