What happens on either side of the equilibrium line in a glacier?
A) sublimation occurs only above the line and melting occurs only below the line
B) melting occurs only above the line and sublimation occurs only below the line
C) above the equilibrium line, the amount of accumulation exceeds the amount lost by various processes
D) air temperatures are below freezing below the line and above freezing above the line
Sublimation
The process by which material moves from a solid phase directly into a vapor, as occurs when a glacier loses ice molecules directly to the air.
Equilibrium Line
The zone in a glacier where the losses of ice and snow balance the accumulation of ice and snow.
Accumulation
The process of materials or energies gathering together over time, often resulting in a gradual increase in amount or the formation of a new structure.
