Which increased outcome occurs when heavy agricultural irrigation overlies karst?

💡 Explanation

Increased irrigation accelerates the chemical weathering of carbonate bedrock by *dissolution*, because greater water flow transports more carbonic acid through the karst system; therefore, aquifer contamination risk increases, rather than improving precipitation or salinity, directly impacting water quality.
