The sun gives energy and the earth receives the sun’s energy. The way the earth interacts with the sun’s energy can be displayed in a picture called the earth’s energy budget(预算). It displays the sun’s energy that reaches us and how much of that energy is taken in and how much is thrown back by the earth and its air. Once the energy reaches the earth, some of it is taken by land and oceans. The amount of energy that is taken in influences the temperatures. The energy that is not taken in is thrown back to space.

Generally, the amount of energy coming in is equal to the amount of energy going out. So, we say the earth’s energy budget is balanced. If more energy was coming in than was going out, the earth’s temperature would increase. On the other hand, if too much energy is thrown back, and not taken in, we would see the earth’s temperature dropping.

Of all of the sun’s energy that hits the earth, about 67% is taken in by the land, oceans, air and clouds and about 33% is thrown back into space.
