Question 1

1.

The velocity of ice movement is primarily controlled by:

slope of bedrock surface

amount of sediment at the terminal moraines

length of the glacier

size of hte sediment transported by the glacier

Question 2

2.

Over a period of years, a 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.

Question 3

3.

The downhill movement of mountain glaciers is primarily caused by:

evaporation of ice directly from the glacier

snow blowing across the top of the glacier

the force of gravity pulling on the glacier

water flowing over the glacier

Melting glaciers are known to deposit sediments that are described as
