Reflectivity of earth
Webof the reflectivity of Earth's surface. • Energy absorption: In the case of Earth’s energy balance, it is the amount of light energy from the Sun converted into heat energy absorbed by the surface features of Earth (plants, earth, water) and its atmosphere. The energy that is not absorbed is reflected back out into the atmosphere. WebMay 14, 2024 · This reflectivity, called albedo, is one key way Earth regulates its temperature – if Earth absorbs more energy than it reflects, it gets warmer, and if it reflects more than it absorbs, it gets cooler. The picture becomes more complicated when scientists bring the other wavelengths into the mix. In the near-infrared part of the spectrum ...

WebAveraged annually over Earth’s entire surface, the Sun provides about 345 watts per square metre of energy. About 30 percent of this energy is reflected away to space and is never used in the Earth-atmosphere system. Of that which remains, a little less than 1 percent (3.1 watts per square metre) accelerates the air by generating winds. WebOf all of the solar radiation reaching Earth, 30% is reflected back to space and 70% is absorbed by the Earth (47%) and atmosphere (23%). The heat absorbed by the land and …
