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.(4 points)

Answer 1

Weathering is the process by which rocks and landforms are broken down into smaller fragments due to the action of elements such as water, wind, and temperature changes. Over time, this fragmentation weakens the rock structure and creates openings and cracks. Erosion, on the other hand, involves the transportation of these weathered fragments by agents such as wind, water, and ice. In the case of sea arches, weathering weakens the coastal cliffs, causing the formation of cracks and cavities. Erosion then wears away the weakened rock, creating a hole or arch through which waves can pass. In the case of sea stacks, weathering and erosion contribute to the formation of an isolated pillar of rock. Weathering weakens the coastal cliffs, forming steep rocky outcrops. Erosion then wears away the surrounding rock, leaving behind a freestanding stack.
