Question

Which of the following happens when the rate of forward motion of a glacier is slower than the rate of ablation? A. The glacier remains stationary B. The glacier sheds an iceberg C. The glacier advances D. The glacier retreats​

Answer 1

Answer:

The glacier sheds an iceberg when the rate of forward motion of a glacier is slower than the rate of ablation.

Explanation:

The base of glacier moves slower than the surface. The edges are affected by friction more move along the sides, hence they move more slowly than the center of the glacier. If the rate of forward motion of the glacier is slower than the rate at which it is melting i.e ablation, an iceberg is shed that moves forward.

Its timely retreat or advancement depends on the rate at which it snows or melts. This refers only to the terminus or snout of the glacier. Even if it retreats. The glacier deforms and moves downward.
