In what form is radiation emitted from the earth's surface back into the atmosphere?
As light
As greenhouse gases
As gamma rays
As heat
What might happen if the greenhouse effect didn't exist?
It would be too cold for humans to survive on the earth
The earth's temperature would be much more comfortable
The sun's rays would never reach the surface of the earth
