- Geography - glaciers
- Slow-moving rivers of ice
- Formed in upland areas where snow accumulates to over 15m deep
- Snow compressed to form ice (firn)
- End of glacier is a snout
- Gravity causes glaciers to flow downhill - 30cm a day
- Crevasses are deep cracks in a glacier
- Glacial surge is a rapid advance of a glacier - 10-100m a day
- Caused by a build-up of meltwater which reduces friction
