Answer to Question 1

Answer: Ice does not become a glacier until it moves under its own weight. This occurs when the ice mass reaches a critical thickness of approximately 50 meters and the weight of the overlying ice causes the ice at the base to deform plastically and flow downslope.

Answer to Question 2

Answer: Both can reveal the direction of ice flow. They differ in how they formed. A roche moutonnee is an erosional featureeroded out of bedrock by continental glaciation, and a drumlin is a depositional feature formed of glacial till.
