D)evaporation

Question

Quizplus · Accepted Answer

Radiation is the transfer of heat through electromagnetic waves, such as light. As the lizard sits on the rock and basks in the sun, it absorbs the radiant energy coming from the sun to raise its body temperature. Conduction involves the transfer of heat through direct contact between two objects, which is not the case here. Convection involves the transfer of heat through the movement of fluids, such as air or water, which is also not applicable in this scenario. Evaporation involves the transfer of heat through the evaporation of water, which is not relevant to the lizard's attempt to raise its body temperature.
