What causes water to become "hard," other than freezing? What will be an ideal response?
Calcium and magnesium ions cause water to be hard. These originate in limestone and dolomite rock,
otherwise known as carbonate rock. They are liberated into solution by dilute carbonic acid, which
forms by the reaction of atmospheric carbon dioxide with rainwater. Dissolving of carbonate rock in
this manner hardens groundwater and also produces caverns and their spectacular features.
