1. Notch: An undercut base of a cliff formed by wave erosion is an erosional feature.
2. Sea Arch: An archway formed in a headland by wave erosion is an erosional feature.
3. Cliff: A steep rock face often formed by the erosive action of waves on a coastline is an erosional feature.
4. Hook: A hook is a type of spit where the end is curved inwards due to wave refraction or opposing currents. A spit is a depositional feature made of accumulated sediment. Thus, a hook is fundamentally depositional.
Therefore, 1, 2, and 3 are coastal erosional features.
