What type of solar radiation does not reach the surface of the Earth and what happens to solar radiation that reaches Earth surface but is not reflected back into space?
UVC rays do not reach the Earth's surface because they are completely absorbed by the atmosphere. Gamma radiations are produced by the Sun as a result of nuclear fusion reactions but these radiations have a very low wavelength and are unable to reach the Earth's Surface. All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat. Snow and ice, airborne particles, and certain gases have high albedos and reflect different amounts of sunlight back into space. Low, thick clouds are reflective and can block sunlight from reaching the Earth's surface, while high, thin clouds can contribute to the greenhouse effect. The Earth absorbs most of the energy reaching its surface, a small fraction is reflected. In total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth's surface while around 30% is reflected back to space and does not heat the surface. Atmospheric gas molecules and aerosols deflect solar radiation from its original path, scattering (reflecting) some radiation back into deep space and some toward Earth's surface. Clouds reflect much more incoming solar radiation than they absorb. The Earth absorbs most of the energy reaching its surface, a small fraction is reflected. In total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth's surface while around 30% is reflected back to space and does not heat the surface. Some sunlight is reflected back into space, but some is absorbed by Earth's atmosphere and surface. Energy radiated from Earth's surface as heat, or infrared radiation, is absorbed and re-radiated by greenhouse gases, impeding the loss of heat from our atmosphere to space.The Earth absorbs most of the energy reaching its surface, a small fraction is reflected. In total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth's surface while around 30% is reflected back to space and does not heat the surface. Not all of the Sun's energy that enters Earth's atmosphere makes it to the surface. The atmosphere reflects some of the incoming solar energy back to space immediately and absorbs still more energy before it can reach the surface. The remaining energy strikes Earth and warms the surface.
