How waves erode

Spits

1.Hydraulic action: is the power of water as it crashes against the coast

Bars

Tombolos

2. Compressed Air : becomes trapped in rock cracks by incoming waves. The pressure of the air can shatter the rock

Lagoon

3. Abrasion: is erosion of the coastline by the stones that are hurled against it by the waves

:A sea cliff is a high rock face that slopes very steeply up from the shore

1: Waves erodes notch in the coast

2: The notch gradually becomes deeper

3:The are above the notch becomes so undercut that it collapses, forming a cliff

Attrition: The stones carried by waves are themselves smoothed and worn down.

4:The former base of the cliff remain as a wave -cut platform

5:Material eroded from the cliff builds up to form a wavebuilt terrace

Examples: The Cliffs of Moher, Co Clare
