Destructive wave
Destructive waves are created in storm conditions. They are created from big, strong waves when the wind is powerful and has been blowing for a long time. They occur when wave energy is high and the wave has travelled over a long fetch.
1 of 6
Constructive wave
They are created in calm weather and are less powerful than destructive waves. They break on the shore and deposit material, building up beaches. They have a swash that is stronger than the backwash. They have a long wavelength, and are low in height
2 of 6
Hydraulic action
Air may become trapped in joints and cracks on a cliff face. When a wave breaks, the trapped air is compressed which weakens the cliff and causes erosion.
3 of 6
Abrasion
Bits of rock and sand in waves grind down cliff surfaces like sandpaper.
4 of 6
Attrition
Waves smash rocks and pebbles on the shore into each other, and they break and become smoother.
5 of 6
Solution
Acids contained in sea water will dissolve some types of rock such as chalk or limestone.
