Question

Quizplus · Accepted Answer

The visible snowline across the surface of a glacier is called a firn line. This is the point at which snow and ice accumulation balance out with loss due to melting or sublimation. The equilibrium line refers to the point where there is no net gain or loss of ice over time, while medial moraines are ridges of rock debris that form in the middle of glaciers from the merging of two glaciers with lateral moraines. The term "ice line" is not commonly used in glaciology.
