A huge mass of ice slowly moving over a land mass like a river.

The Albedo Effect
1. White surfaces, e.g. ice/snow, reflect more heat hence less heat is absorbed. 2. This effect snowballs until a lot of ground is covered by snow or ice.
2 of 7
Ice Age
A perioed when ice sheets cover large areas of the world.
3 of 7
Interglacial Period
A perioed between Ice Ages (we are in one!).
4 of 7
Firn or Neve
Blue Ice, formed from compacted snow, as the snow is compacted air is squeezed out of the snow creating blue ice.
5 of 7
Internal Friction
Sheets in glaciers slide over each other.
6 of 7
Basal Sliding
The friction between the glaciers and the ground creates heat which melts 1-2cm of the bottom of the glacier, causing it to slide.
