1
Q
What causes ice movement
A
Gravity
2
Q
What is the accumulation zone
A
The build up of ice mass from downslope movement
3
Q
What affects the rate of movement of a glacier
A
Temperature of ice
Wether pressure melting point is reached
4
Q
Warm based (temperate) glaciers rate of movement
A
Will reach the pressure melting point and therefore produce a great deal of meltwater which lubricates and increases rate of movement
5
Q
Cold based (polar) glaciers rate of movement
A
Too cold to reach pressure melting point meaning they’re frozen onto bedrock
6
Q
Basal slip
A
Basal sliding is the act of a glacier sliding over the bed due to meltwater under the ice acting as a lubricant
