Match the vocabulary term with the definiton.

• Convection Current

• is energy that is transferred between two objects of different temperatures that move continuously in a predictable pattern, from warmer site to a cooler site, until all sites have reached the same temperature.

• The Law of Conservation of Energy

• is a circular movement of fluids caused by rising of hotter, less dense fluid and the falling of cooler, denser fluid.

• Heat

• Scientific Law that states energy can neither be created nor destroyed.
