On valley flanks in mountainous areas, which erosional outcome results from intense freeze-thaw cycles?

💡 Explanation

Glacial cirque formation occurs because nivation, amplified by differential weathering, leads to the erosion of bedrock; therefore, a bowl-shaped depression forms, rather than fluvial or depositional landforms forming from meltwater.

• Which consequence results near the coast when excessive groundwater extraction destabilizes karst?
• Which consequence results when freeze-thaw cycles saturate soil?
• Which outcome occurs when a coastal headland collapses supporting a sea stack during high tides?
• Which outcome increases erosion in karst regions because of accelerated chemical weathering?
• Which outcome arises because of continental-scale thermal differences intersecting planetary rotation?
• Which outcome results when river meander sinuosity nears cutoff?
