The reason this happens is that salt is hygroscopic. Hygroscopic means that salt absorbs water vapor from the surrounding air. Eventually, the salt attracts enough water vapor that the gas changes into liquid, and the salt partially dissolves and starts to clump together. To combat this tendency, manufacturers put additives in salt that keep it from liquefying.
