Waves smash rocks and pebbles on the shore into each other, and they break and become smoother.
1 of 12
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.
2 of 12
Corrosion/Solution
Chemical reaction occurs when slightly acid water dissolves calcium, breaking down rock such as limestone
3 of 12
Corrasion/Abrasion
Wearing away of the river bed and banks by the load hitting against them.
4 of 12
Delta
Where a river breaks into many distributaries before it reaches the sea
5 of 12
Flood Plain
Flat area next to a river that is liable to flood
6 of 12
Longshore Drift
The movement of material along a coastline by the action of the waves
7 of 12
Backwash
The movement of water down the beach by the action of gravity
8 of 12
Swash
The force of breaking waves moving up a beach
9 of 12
Surface Runoff
All water flowing on the Earth's surface
10 of 12
Through Flow
Movement of water through the soil
