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 by which rocks and other materials are broken down into smaller fragments through physical or chemical means. Erosion, on the other hand, involves the transport of these fragmented materials by wind, water, or ice. In the case of sea arches, weathering weakens the rock along a joint or fault, causing it to erode and create a tunnel-like opening. Over time, erosion widens and deepens this opening, forming a sea arch. Sea stacks, on the other hand, are formed when erosion continues to wear away the land around a sea arch, eventually separating it from the mainland. Deposition then comes into play as the eroded materials are transported and eventually deposited elsewhere along the shoreline, shaping its overall form and composition.
