Evidence of erosion by waves on rocky coasts can be seen in several landforms, including:
-
Sea Caves: These are formed when waves erode softer rock along fractures in the harder rock, creating cavities.
-
Sea Arches: When sea caves erode further and connect through a headland, they can create natural bridges known as sea arches.
-
Sea Stacks: When a sea arch collapses due to continued erosion, it can leave behind isolated rocky pillars called sea stacks.
-
Cliffs: Erosion can shape steep cliffs along the coastline, often creating vertical rock faces.
-
Wave-cut Platforms: These are flat areas of rock at the base of cliffs that are formed as waves erode the base of the cliff, leading to the eventual retreat of the cliff face.
All of these landforms provide clear evidence of the erosional processes that occur as waves continuously impact rocky shorelines.
