Question

Describe the Erosional landforms of Sea.

Answer 1

Some of the erosional landforms of sea waves are sea cliff, sea cave, arch, stack, beach, bar and spit, and wave-cut platform.

1. Sea Cave: Prolonged wave attack on the base of a cliff erodes rock materials, which results in the formation of caves.
2. Sea Arch: When two caves approach one another from either side of a headland and unite, they form an arch, e.g., Neil Island, Andaman, and Nicobar.
3. Sea Stack: Further erosion by waves ultimately leads to the total collapse of the arch. The seaward portion of the headland will remain as a pillar of rock known as a stack. Eg the Old man of Hoy in Scotland.
4. Sea Cliffs: Sea cliffs are steep rock faces formed when sea waves dash against them. The rocks get eroded to form steep vertical walls.
5. WaveCut Platforms: Flat surfaces found at the foot of sea cliffs are called wave-cut platforms. Wave cut platform is also referred to as beach, shelf, terrace, and plain.
