Which outcome increases within limestone caves when plant root respiration elevates?

💡 Explanation

Increased root respiration releases more CO2 into the soil, raising carbonic acid levels, which promotes calcium carbonate weathering through chemical dissolution; therefore, cave weathering rates increase, rather than deposition, because acidity rises.
