What is the difference between silicone and caulking?

The main difference between a caulk and a sealant is elasticity. Caulks are fairly rigid when dry, and are intended for use in areas with minimal expansion and contraction. Sealants are made from flexible material--most commonly silicone--making them ideal for areas prone to expansion and contraction.
