Global Warming
By Patti Hutchison |
|
1 You know that the sun is the source of all energy on earth. But sometimes we get a double dose of that energy. Solar radiation reaches the earth. The earth soaks up some of it and reflects some back to the atmosphere. The reflected radiation is absorbed by the gases in the atmosphere. The gases act like the glass walls of a greenhouse. They trap the warm air in and reflect it back to earth again. Scientists call this the greenhouse effect.
