Answer to Question 1

Answer: Glaciers erode rock by scraping, plucking, and grinding underlying rock into sizes ranging from boulders to fine dust. Alpine glaciers erode cirques, horns, and aretes at their heads; U-shaped valleys and hanging valleys in their main courses; and fjords where glaciers end their journey at the sea. Continental glaciers erode the land surface that they cover, smoothing and rounding the entire underlying topography.

Answer to Question 2

Answer: B
