Albedo.
Radiation
Methane is a greenhouse gas and it absorbs infrared radiation that is remitted from the earth. As it absorbs the radiation it is stopping it from being re-radiated to space thus warming the earth.
Light is electromagnetic radiation. It does not need a medium to support it.
No, Earth's atmosphere does not block all UV radiation from space. It does absorb a portion of the UV radiation, particularly the most harmful UV-C rays. However, UV-A and UV-B rays are able to penetrate the atmosphere to some extent and reach the Earth's surface.
Albedo.
The sun does not reflect its radiation into space.
Radiation from the sun warms the earth. Increasing amounts of greenhouse gases prevent this heat from reflecting back out into space, causing a global warming of the atmosphere.
The atmosphere is heated chiefly by radiation from Earth's surface rather than by direct solar radiation because about 50 percent of the solar energy is absorbed at Earth's surface. 30 percent is reflected back to space. 20 percent is absorbed by clouds and the atmosphere's gases.
Earth loses energy to outer space through radiation.
90% of radiation reaching the surface of the earth is absorbed! and 10% is reflected into space.
If all the radiation from space reached Earth we would all die in a matter of minuets
Because radiation is particles.
Radiation is the transfer of heat energy through space by electromagnetic radiation. Most of the electromagnetic radiation that comes to the earth from the sun is invisible. ... In electromagnetic radiation, its frequency is the number of electromagnetic waves moving past a point each second.
It increases the amount of solar radiation that is reflected into space
Radiation budget is Earth's atmosphere. The Earth's atmosphere has more solar energy than it radiates back to space.
Earth loses heat energy to outer space mainly by radiation.
