How much light does the earth reflect
WebDoes the Earth reflect heat? 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. The Earth radiates energy at wavelengths much longer than the Sun because it is colder. ... Does Earth’s surface give off light at ... WebAnswer (1 of 3): Short answer: half of Earth.
