The song was heard in Disney's Phineas and Ferb: The Best LIVE Tour Ever!, and also was used in the Phineas and Ferb's Rockin' Rollin' Dance Party show at Disney California Adventure. S.I.M.P.

The atmosphere is heated chiefly by radiation from Earth's surface rather than by direct solar radiation because about 50 percent of the solar energy is absorbed at Earth's surface. 30 percent is reflected back to space.
Answers. Best Answer: radiation from the sun is the main source of heat for the earth. It travels from the sun in the form of electromagnetic radiation (light, uv rays, ir rays etc) when these rays hit molecules they transfer energy, and cause them to heat up. Think about it this way... mercury is a very hot planet... pluto is not... more solar radiation = hotter planet.
