The diagram represents a stream valley. Which diagram below best shows how this valley might be modified after a glacier has moved through it?
A _____ is an oval mound of unsorted sediment (till). It shows the direction of glacial movement.

The photograph shows scratched and grooved
bedrock with boulders on its surface. The scratches and grooves were most likely created when
alternating thawing and freezing of water cracked the bedrock
flooding from a nearby lake covered the bedrock
a glacier dragged rocks over the bedrock
rocks from a landslide slid along the bedrock
Base your answer to the following question on the diagram which represents a profile of a mountain glacier in the northern United States. Over a period of years, this glacier gains more snow mass than it loses. What will be the most likely result of this gain?
The glacier will decrease in size, and the ice front will retreat.
The glacier will decrease in size, and the ice front will advance.
The glacier will increase in size, and the ice front will retreat.
The glacier will increase in size, and the ice front will advance.
