Which mechanism forms bowl-shaped depressions specifically called cirques?

💡 Explanation

Glacial cirques form by rotational sliding erosion because the glacier's basal ice melts and slides, eroding bedrock; therefore, the glacier carves a bowl-shape rather than features created by stream erosion or tectonic upheaval.

• Which consequence results when tephra accumulation exceeds capacity?
• Which environmental shift occurs following a large composite volcano eruption's pyroclastic surge?
• Which outcome occurs when reduced atmospheric pressure differences weaken trade winds?
• Which mechanism causes increased stream meandering in regions where the jet stream weakens and becomes more zonal?
• Which outcome occurs when hydraulic action erodes steep sea stack faces?
• Which thermal consequence arises where oceanic crust subducts beneath continental crust?
