The zone of accumulation.
The middle layer of a glacier is called the "firn zone". This layer is composed of partially compacted snow that is in the process of being transformed into ice. The firn zone is found between the surface snow accumulation zone and the deeper layers of glacier ice.
The zone above the water table where water is suspended is called the unsaturated zone or vadose zone. This zone contains both air and water in the soil or rock pores.
The zone above the water table is called the unsaturated zone or vadose zone. This area contains both air and water, with the water content decreasing as you move up towards the surface.
The zone of fracture experiences tension hen the glacier moves over irregular terrain. This tension results in gaping cracks called crevasses. Crevasses can be 50 meters deep. They are often hidden by snow and make travel across glaciers dangerous.
Zone of ablation is the area of a glacier where there is a net loss of ice due to melting, sublimation, and calving, while the zone of accumulation is the area where snowfall exceeds melting and forms new ice. In the zone of ablation, the glacier's terminus retreats, while in the zone of accumulation, the glacier advances. The zone of ablation typically occurs at lower elevations and is characterized by a negative mass balance, whereas the zone of accumulation is found at higher elevations with a positive mass balance.

a glacier has a snowline at the same height as the wastage line.
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.
The upper part of a glacier is called the accumulation zone. This is the area where snow accumulates and feeds the glacier, eventually turning into ice and flowing downhill towards the glacier's terminus.
The area of a glacier where losses of ice exceed the addition of snow is called the ablation zone. In this zone, melting, sublimation, and iceberg calving typically occur at a higher rate than snow accumulation. This can lead to glacier retreat and overall shrinking of the glacier.
The middle layer of a glacier is called the "firn zone". This layer is composed of partially compacted snow that is in the process of being transformed into ice. The firn zone is found between the surface snow accumulation zone and the deeper layers of glacier ice.
it is called the pelagic zone.
The area that is melting faster than it is accumulating is the "Zone of Ablation." The very bottom end of a glacier is typically called its "foot."
The zone above the water table where water is suspended is called the unsaturated zone or vadose zone. This zone contains both air and water in the soil or rock pores.
The 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.
