Question

glaciers erode land through which two processes?
o chemical weathering and deflation
o deflation and abrasion
o plucking and abrasion
o plucking and deflation

Explanation:

• Plucking: Glaciers freeze around rocks and pull them out of the ground.
• Abrasion: Rocks frozen in the glacier scrape and grind the land as the glacier moves.
• Chemical weathering: Involves chemical reactions (not main glacier erosion).
• Deflation: Wind - related (not glacier - related).

Answer:

plucking and abrasion
