Which consequence results when increased rainfall saturates unconsolidated sediment above karst bedrock?

💡 Explanation

Over-saturation causes loss of strength, which forms sinkholes through suffosion. Gaps in the bedrock allow sediment to wash away because pore pressure increases due to rainfall, therefore overburden collapses rather than soil creep being more stable.

• Which feedback arises when increased rainfall rapidly saturates soluble bedrock, forming new sinkholes?
• Which weather outcome results when cold air masses obstruct atmospheric river streams over mountainous terrain?
• Which mechanism dictates the spacing of strike-slip faults within transform fault zones on continents?
• Which consequence results when differential weathering weakens strata?
• Which mechanism causes oxbow lake formation when a river's meander neck narrows during floodplain evolution?
• Which phenomenon primarily causes uplift along a reverse fault zone?
