The simulated flow progresses smoothly,
but the glacier's actual speed would vary. Glaciers
move more quickly when temperatures are warmer. They

up as they move down steep areas.
5. Why do you think the center of the glacier
moves faster than the sides?
6. Describe what the movement of the Mathes
Glacier might feel like if you were camped in the middle
