- A glacier is a mass of ice which flows down a valley.
- Glaciers form when the climate becomes cold enough for precipitation to fall as snow.
- The weight of the new snow lying on the surface compresses the underlying snow and this turns to ice.
- When the ice starts to move downhill because of gravity is called a glacier.
- The weight of the new snow lying on the surface compresses the underlying snow and this turns to ice.

- Erosion- The wearing away of the land at the top of the mountains and in valleys where the glacier flows.
- Transportation- the movement of eroded material down the mountains
- Deposition- The dumping of eroded material lower down the mountain
- Abrasion- is when the pieces of jogged rock and gravel carried away by the glacier rub against, and wear away, the valley sides and floor of a valley.
- Plucking- is when the glacial ice freezes onto solid rock. As the glacier moves, large pieces of rock are pulled away with it.
