- a glacier is a large body of ice formed from compressed snow. They slowly down hill under there own weight and gravity.
- there are 3 types of glacier:
- valley/mountain glacier- these are like giant rivers of ice that flow slowly down a mountain or valley from the snowline above.
- ice sheet- these are the largest type of glacier they can be 2-3 km thick so they completely cover the landscape so very few landmarks can be seen. They are found in Antartica and Greenland.
- ice field- these are mini ice sheets and can be up to 50,000km2. They form in plateau like uplands.
