Which outcome occurs when infiltrating acidic groundwater reaches caves?

💡 Explanation

Enhanced speleothem formation occurs because infiltrating acidic water causes deposition of dissolved calcium carbonate via the 'common-ion effect'; therefore, carbonate precipitation increases, rather than saline/silicate deposits, since acidity favors carbonate dissolution upstream.
