How did erosion shape this glacial feature? (Hint: It is bedrock.)

Question

Quizplus · Accepted Answer

Both plucking and abrasion were likely involved in shaping this glacial feature. Plucking occurs when the glacier freezes onto and pulls rocks and other debris out of the bedrock as it moves. Abrasion occurs as the particles carried by the glacier scrape and carve the bedrock as the glacier moves over it. The combination of these processes would be the most likely explanation for the shape of this glacial feature.
