Tony is studying how heat is distributed throughout Earth. He learns that heat energy is transferred by three mechanisms throughout Earth’s systems. It is transferred by radiation, convection, and conduction. On the lines below the pictures, label each model with a word from the word bank that describes the type of energy transfer represented. radiation • convection • conduction
