JudyThe equilibrium line of a glacier is the boundary where there is an equal balance between the amount of ice gained through snow accumulation and the amount lost through melting or iceberg calving. It divides the accumulation zone (above the equilibrium line) from the ablation zone (below the equilibrium line). Glaciers will advance or retreat depending on the position of their equilibrium line.

Which parts of glaciers and its triburitaries moves most quickly?
The center of a glacier and its tributaries usually move faster than the edges due to the ice flow being concentrated in the middle. This is known as glacier flow dynamics, where the center is under more pressure due to the mass of ice pushing down on it.
What is The line dividing the zone of accumulation from the zone of ablation on a valley glaciers is called?
The line dividing the zone of accumulation from the zone of ablation on a valley glacier is called the equilibrium line. This line marks the point where accumulation (snowfall) equals ablation (melting and sublimation), influencing the glacier's overall mass balance and movement.
What situation allows a glaciers size to be maintained?
a glacier has a snowline at the same height as the wastage line.
An ice front is likely to be stationary when the glacier does what?
An ice front is likely to be stationary when the rate of ice accumulation in the glacier matches the rate of ice loss due to melting or calving at the front. This equilibrium state is known as a stable glacier front, where there is no net advance or retreat of the ice front.
How much of a glacier is above the water line?
Over 90% of an iceberg's volume (and mass) is underwater. Therefore 10% is above the water.A glacier is a flow of ice downhill, driven by snow and ice accumulating in the mountains. When a part of the glacier breaks off and begins to float on the sea, it becomes an iceberg.
