Which effect increases in glacial meltwater when subglacial limestone dissolution accelerates?

💡 Explanation

Increased dissolution of limestone raises calcium and bicarbonate concentrations; therefore, increased downstream carbonate mineral precipitation occurs due to exceeding saturation, rather than silicate weathering changes or pH effects because mineral equilibrium shifts favor precipitation.
