Which effect accelerates karren formation on limestone outcrops?

💡 Explanation

Faster dissolution amplifies surface irregularities; chemical weathering of limestone promotes increased surface area, which in turn increases the dissolution rate by positive feedback, because it creates more reactive spots. Therefore, localized dissolution intensifies, rather than uniform erosion from climate or heat.
