| Erosion | When material is broken down and the eroded material is moved away. |
| Hydraulic Action | When waves push water in to cracks in rocks and trapped air (under pressure) forces the cracks further apart. |
| Abrasion | When waves hurl fragments of rock at a cliff face. |
| Attrition | When rocks collide and break up into small pieces. |

| Chemical weathering | When weak acids in rain water dissolve rocks. |
| Biological weathering | When animals and plants break up rocks into smaller pieces by burrowing into them or through the growth of their roots. |
| Traction | Heavy particles rolled along the seabed. |
