Presentation on theme: "Chapter 2 Section 1 The sun provides nearly all of the energy which powers the atmosphere. That energy comes to us in the form of electromagnetic."— Presentation transcript:
About 50% of energy is absorbed by the surface. The absorbed energy is then reradiated back into the atmosphere. This energy is then absorbed by greenhouse gases and reradiated again, thus maintaining the Earth’s warmth.
Greenhouse gases trap heat in the atmosphere keeping it warm. If there’s too much of such gas in the atmosphere the temperature will rise.
