Question

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

Explanation:

To solve this, we recall glacial erosion processes. Glaciers erode via plucking (freezing water lifts rocks) and abrasion (rock fragments grind bedrock). Chemical weathering is not a main glacial erosion process, and deflation is a wind erosion process. So the correct option is the one with plucking and abrasion.

Answer:

C. plucking and abrasion (assuming the options are labeled A - D with this as option C; if original labels differ, adjust, but based on content, the correct pair is plucking and abrasion)
