Glacier System Flashcards
1
Q
Where do inputs come from?
A
Avalanches along the sides of the glacier but mainly from precipitation as snow
2
Q
Under the flow of gravity how does the glacier flow?
A
Downhill
3
Q
What are the main outputs from the glacier
A
Meltwater and evaporation
4
Q
What is accumulation?
A
In winter, more is added to the glacier system than is lost. It happens near to the head of a glacier and leads to a zone of accumulation and can cause the glacier to advance
5
Q
What is accumulation in simple terms?
A
Inputs are bigger than outputs
6
Q
What is ablation in simple terms?
A
Outputs are more than inputs
7
Q
What is ablation?
A
In summer and lower altitudes, more is lost from the glacier system than is added which leads to a zone of ablation and can cause the glacier to retreat
