Which outcome occurs when intense tropical rainfall accelerates weathering?

💡 Explanation

Intense rainfall promotes increased eluviation, a form of leaching, because it removes clay minerals from upper soil horizons. This mechanical process transports materials, therefore reducing clay in the A and E horizons rather than affecting oxidation, humification, or silicate precipitation.

• Which outcome is MOST LIKELY when heavy rainfall exceeds natural levee infiltration capacity along a major river?
• Which outcome during stratovolcano eruption increases landslide risk?
• Which outcome occurs when glacial meltwater breaches moraine deposits?
• Which mechanism causes high-altitude subtropical streams (jet streams) to steer mid-latitude cyclonic storm systems?
• Where does the formation alluvial fans often occur when a river empties into a lake?
• Which outcome occurs when a steep mountain slope underlying a glacial cirque thaws, exceeding its angle of repose?
