Which mechanism causes increased landscape denudation following repeated freeze-thaw cycles in alpine environments?

💡 Explanation

Cryoclasty causes denudation because repeated ice crystal growth within rock fractures exerts pressure, thereby weakening and fragmenting the bedrock. This leads to increased physical weathering, rather than chemical weathering outcomes from oxidation, hydrolysis, or carbonation occurring on different substrates.

• Which outcome occurs when substantial Antarctic ice sheet melting increases freshwater input into the Southern Ocean?
• Which outcome follows increased rainfall intensity on soils?
• Which effect results as global air masses approach pressure gradients?
• Which effect results when intensifying trade winds strengthen the subtropical gyres in the Pacific Ocean?
• Which risk increases when pyroclastic flows encounter saturated ground?
• Near coastlines underlain by limestone, which risk to underground freshwater aquifers increases due to storm surges?
