Earth's Energy Balance extended definition. Earth's Energy balance describes how the incoming energy from the sun is used and returned to space. If incoming and outgoing energy are in balance, the earth's temperature remains constant.
Heat Transfer. Practically all of the energy that reaches the earth comes from the sun. Intercepted first by the atmosphere, a small part is directly absorbed, particularly by certain gases such as ozone and water vapor. Some energy is reflected back to space by clouds and the earth's surface. Most of the radiation, however, is absorbed by the surface. Energy is transferred between the earth's surface and the atmosphere in a variety of ways, including radiation, conduction, and convection. The graphic below uses a campstove to summarize the various mechanisms of heat transfer.
