The difference is important in environmental science.
Sometimes neither atom can give us information about ancient climates.
18O is more massive than 16O because it contains two hydrogen atoms.
In hot climates, where there is plenty of evapora equally and hold the atoms together, the higher-mass H can evaporate into the air more easily.
