Which outcome occurs when intense rainfall weakens soil above karst?

💡 Explanation

Localized subsidence, or sinkholes form, due to soil washouts along fractures; rainwater dissolves limestone creating cavities leading to ground collapse due to the mechanism of solution weathering, because rainwater is naturally acidic; therefore sinkholes appear, rather than other effects from overloaded soil.
