Which primary effect accelerates topsoil horizon formation (pedogenesis) when exposed volcanic ash deposits experience high precipitation?

💡 Explanation

Increased precipitation promotes enhanced chemical weathering because hydrolysis and dissolution reactions breakdown minerals faster, therefore accelerating soil development through pedogenesis, rather than the volcanic substrate remaining inert with slow breakdown.
