Which situation allows a glacier’s size to be maintained?

The extent of a glacier is maintained by glacier budget. It is a balance between the amount of ice accumulate or lost from the glacier by ablation. The ablation can occur because of factors like melting, sublimation and breaking of ice.

Therefore, the situation which allows a glacier's size to be maintained is the amount of snow accumulates to the amount of snow undergone with wasting or loss.
