Energy transformations.

The cycle starts with the sun, the source of all energy. Then, the corn on the earth transforms radiant energy into chemical enegry which is dormant until activated. At a factory, the corn is transformed into a liquid form which is able to be transformed into other forms of energy. Inside the car, the chemical energy turns into thermal energy by the sparks. Then, when the fuel explodes in the cylanders, thermal energy turns into kinetic energy which moves the car.

The cycle starts with the sun, the source of all energy. The difference of air pressure (caused by the uneven heating of the Earth) causes wind. The thermal energy of the sun is transformed into kinetic energy. Then, the wind turbines tcapture that kinetic energy through a turbine. The generator transforms the kinetic energy into electrical energy. That electrical energy flows through wires which power light bulbs. The light bulbs transform electrical energy into radiant and thermal energy.
