Which mechanism amplifies cirque erosion nearing sea level?

💡 Explanation

Increased freeze-thaw at sea-level cirques causes intensified erosion because water repeatedly freezes and expands within rock fissures, driving frost wedging. This physical weathering is therefore magnified near sea-level rather than geothermal or deep weathering processes.
