sea arches and sea stacks provide evidence of weathering and erosion. In three to 5 sentences explain the roles in weathering and erosion play in creating these landforms.
Weathering and erosion contribute to the formation of sea arches and sea stacks. Weathering breaks down the rock along coastal areas through processes like freeze-thaw, where water seeps into cracks, freezes, and expands, causing the rock to weaken and break. Erosion then removes the broken pieces of rock, carrying them away and leaving behind gaps or holes that may eventually form sea arches. Over time, continuous erosion can cause the collapse of the sea arch, leaving behind a sea stack – a tall pillar of rock that once connected to the mainland.
