Solar Radiation: How Sunlight Heats the Planet
Earth relies on solar radiation to heat the planet. Overall, it depends on how much energy enters and leaves the planet''s system. When the sun''s energy is reflected back into space, Earth avoids warming. By releasing solar radiation back into space, Earth cools. When incoming energy from the sun is absorbed by the Earth system, Earth warms.
