What is accumulation?
The input of snow and ice into the glacial system.
Most accumulation is snow.
What is ablation?
The output of water from a glacier.
What is the glacial budget?
The balance between accumulation and ablation over a year - it shows whether the mass of ice in the glacial system has increased or decreased.
This determines whether the front of the glacier advances or retreats.
Where does more accumulation occur?
More accumulation than ablation occurs in the upper part of a glacier - so it’s called the zone of accumulation.
Where does more ablation than accumulation occur?
In the lower part of a glacier - so it’s called the zone of ablation.
What is the glacier’s equilibrium point?
The place where accumulation and ablation are equal.
