Which increased process alters cave stalactite δ18O ratios?

💡 Explanation

Increased isotopic fractionation occurs during evaporation because lighter isotopes evaporate faster; thus, oxygen isotope fractionation causes δ18O ratios to change, therefore the stalactite composition changes due to differing temperature history reflected in oxygen isotope ratios, rather than other chemistry.
