Answer to Question 1

Answer: Frictional drag is simply the slow down of movement due to the contact between two opposing surfaces. Frictional drag slows down a glacier's external movement. The glacier experiences this drag as it encounters the bedrock. So, movement is slowest at the base and at the sides of the glacier.

Answer to Question 2

Answer: Striations are parallel scratches created by glaciers scraping the underlying bedrock. Aligned in the direction of ice flow, striations tell us the past movement of a glacier that has long since receded. By mapping striations on land once covered by continental glaciers, geologist can decipher the flow direction of the ice.
