• Source

The wearing away of rocks by waves that smash along the cliff and wear it away. It is commonly known as the sandpaper effect.

• Attrition

• Hydraulic Action

• Corrosion

• Abrasion

the sheer force of water crashing against the coastline sometimes trapping air and water, increasing pressure causing material to be dislodged and carried away by the sea.

• Attrition

• Hydraulic Action

• Corrosion

• Abrasion

Sometimes called solution, when rock minerals are eroded by weak acids

• Attrition

• Hydraulic Action

• Corrosion

• Abrasion

Rock fragments and sediments in rivers smash together and cause them to become smaller.

• Attrition

• Hydraulic Action

• Corrosion

• Abrasion

Rivers in the upper course wear away rock in this way. These rivers are not wide but narrow.

• Lateral erosion

• Headward erosion

• Upward erosion

• Vertical erosion

Rocks effectively bounce along the river bed due to changes in velocity

• Solution

• Suspension

• Saltation

• Traction
