What is the source of almost all energy in the Earth system? - Answer-Solar Radiation (the sun) Explain the Earth's radiation balance at the top of the atmosphere. - Answer-Qin=Qout (incoming energy must equal outgoing energy) Explain the Earth's surface heat budget. What terms are the most important? - Answer-100 units of solar radiation at the top of the atmosphere, approximately 25% is reflected back to space, 25% is absorbed by the atmosphere, and 50% reaches Earth's surface. Of that...
