Energy can change in two different ways. It can undergo a transfer, or it can undergo a transformation. For each of these exampl
es of how energy is changed, write the correct answer in the blank. In photosynthesis, solar energy undergoes a _______ when it changes from light energy to chemical energy. When the sun warms Earth’s surface, thermal energy is ___________ to land and water.
Energy transfer is the movement of energy from one location to another. For example, when electricity moves from a wall plug, through a charger, to a battery.
Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy.
While energy can be transferred or transformed, the total amount of energy does not change – this is called energy conservation.
