Which is a characteristic of glacial movement?
a. the zone of wastage is at the top of the glacier.
b. movement depends on the balance between accumulation and wastage.
c. new snowfall accumulates in a zone at the bottom of the glacier.

(B) Movement depends on the balance between accumulation and wastage.

Explanation:

A Glacier is accumulation of snow over a particular region over many years. It is balanced by zone of accumulation and zone of wastage. The zone of accumulation is the top of the glacier where the snow or ice accumulates whereas the zone of wastage is the bottom region of the glacier which melts slowly over time. A glacier sustains if the zone of accumulation is greater than the zone of wastage.
