Question

A surface geological process that can create a landform called Cirque is:

• A. aeolian deposition
• B. fluvial deposition
• C. glacial erosion
• D. deposition of volcanic ash

Hint:

Cirques are formed by glacial erosion, where glaciers carve out bowl-shaped depressions in mountainous regions.

Answer 1

The Correct Option is C

A cirque is a bowl-shaped, steep-walled hollow found in mountainous regions, typically formed by the erosion of glaciers. Glacial erosion occurs when glaciers move through the landscape, carving out features like cirques, valleys, and fjords.

Step 1: Analyzing the options.
- (A) Aeolian deposition: This process involves the deposition of material by wind, which does not create cirques.
- (B) Fluvial deposition: This involves water and sediment deposition by rivers, not the formation of cirques.
- (C) Glacial erosion: This is the correct answer, as glaciers carve out cirques through erosion.
- (D) Deposition of volcanic ash: This process does not form cirques.

Step 2: Conclusion.
The correct answer is (C) because cirques are formed by the erosive action of glaciers.

Final Answer: (C) glacial erosion
