  • Sea waves are undulations of sea water with well developed crests and troughs.
  • Crest is the upper part of the wave and trough is the lower part.
  • Wavelength is the horizontal distance between two successive crests or troughs.

2. Work of Sea Waves

  • Sea waves are the chief agent of gradation in coastal areas.
  • The erosional work of sea waves depends on wave size and strength, seaward slope, tidal height range, rock composition, and water depth.
  • Surf waves can exert very high pressure on the shore.

3. Erosional Landforms Formed by Sea Waves

  • A sea cliff is a scarp face of the coast facing the sea.
  • A cliff begins when waves cut a notch at sea level.
  • The notch widens, the overhanging rock is undermined, and the rock collapses to form a cliff.

4. Depositional Landforms Formed by Sea Waves

  • Sea waves deposit the eroded material and build features of accumulation.
  • A beach is formed by deposition of sand, gravel, and pebbles between low-tide level and the coastline.
  • A beach grows when waves are less active and can be destroyed by strong waves.
