The way the Earth interacts with the sun s energy can be displayed in a diagram called the

Earths energy budget. It displays the sun s energy that reaches us and【C1】______of that energy is absorbed and reflected【C2】______the earth and its atmosphere. Solar energy reaches earth as electromagnetic radiation.【C3】______the energy reaches earth, some of it is absorbed by the atmosphere, including clouds. Some of it【C4】______it to the earth s surface, and is absorbed by land and oceans. The amount of energy absorbed affects【C5】______first of all. The energy that is not absorbed by the earth or its atmosphere is reflected back out to space in the same wavelengths【C6】______it came to earth. On average, the amount of energy【C7】______is equal to the amount of energy going out. So, we say the earth s energy budget is【C8】______. If more energy was coming in than was going out, the earth s temperature would【C9】______On the other hand, if too much energy is reflected, and not absorbed, we d see a decrease in the earth s temperatures. Of all of the sun s energy that【C10】______the Earth, about 70% is absorbed by the land, ocean, atmosphere and clouds and about 30% is reflected back into space.
