1. A fall or topple happens when rocks and other sediments fall through the air and land at the bottom of a slope
2. A slide happens when a section of soil or rock suddenly gives way and moves down a slope. The material moves as a single mass along a slippery zone
3.Flows are a mixture of water, rock and sediment. They move very quickly
4. A spread is an extension of a cohesive soil or rock mass combined with a general subsidence of the fractured mass of cohesive material into softer underlying material
5. Topple. This is characterized by the tilting of rock without collapse, or by the forward rotation of rocks about a pivot point. Topples have a rapid rate of movement and failure is generally influenced by the fracture pattern in rock
