Which is not an erosional feature of sea waves?
The correct option is B Beach
The correct answer is option (B) – Beach
Beaches are not the erosional feature of sea waves. They are formed due to the depositional activities of sea waves. The energy of waves produces erosional formations like cliffs, wave cut platforms, sea arches, and sea stacks.
Features formed by Sea Waves
The erosion and deposition of the sea waves gives rise to coastal landforms.
Sea Cliff
- The steep rocky coast rising almost vertically above sea water is called sea cliff.
- Cliffs are very common landscape features. They can form near the ocean (sea cliffs), high in mountains, or as the walls of canyons and valleys.
Sea Caves
Seawaves continuously strike at the rocks. Cracks develop. Over time they become larger and wider. Thus, hollow like caves are formed on the rocks. They are called sea caves.
Sea Arches
As Sea caves cavities become bigger and bigger only the roof of the caves remain, thus forming sea arches.
Stacks
Erosion breaks the roof and only walls are left. These wall-like features are called stacks.
Waves – Important Facts
- The largest waves are found in the open oceans.
- Waves are actually the energy, not the water as such, which moves across the ocean surface.
- Water particles only travel in a small circle as a wave passes.
- Wind provides energy to the waves.
- Wind causes waves to travel in the ocean and the energy is released on shorelines.
- The motion of the surface water seldom affects the stagnant deep bottom water of the oceans. As a wave approaches the beach, it slows down. This is due to the friction occurring between the dynamic water and the sea floor.
- A wave’s size and shape reveal its origin.
- Steep waves are fairly young ones and are probably formed by local wind.
- Slow and steady waves originate from far away places, possibly from another hemisphere.
