How does high permeability of limestone affect karst landforms?
Answer and explanation
Correct answer: Surface runoff decreases and underground drainage increases
High permeability, especially through joints and bedding planes, allows rainwater to infiltrate limestone instead of remaining as surface runoff. Slightly acidic groundwater dissolves the rock and enlarges underground channels, producing caves, sinkholes and underground streams. Therefore option A is correct; the other choices describe unrelated marine, glacial or aeolian processes.
