Yes, about 30% of it goes back.
Volcanic ash in the Earth's atmosphere can reflect sunlight back into space, which can lead to cooling of the Earth's surface. This can contribute to short-term cooling effects on the climate. However, it can also impact air quality and have negative effects on the environment and human health.
About 50% of the sun's radiation that reaches Earth's atmosphere is absorbed by the Earth's surface. The remaining energy is either reflected back to space or absorbed by the atmosphere.
Much of the sun's radiation is reflected back into space by the Earth's atmosphere, clouds, and surface. The atmosphere scatters and absorbs some solar energy, while clouds can reflect sunlight back into space. Additionally, surfaces like ice, snow, and water can also reflect sunlight, a phenomenon known as albedo. Together, these elements play a crucial role in regulating the Earth's temperature and climate.
When solar radiation enters the atmosphere, most of it is absorbed by the Earth's surface. However, about 6 percent of the solar radiation is reflected back into space by the Earth's surface. This reflection occurs mainly from surfaces like ice, snow, and water, which have high albedo, meaning they reflect a significant portion of incoming solar energy.
The sun does not reflect its radiation into space.
Earth's radiation is primarily longwave. Shortwave radiation from the sun enters the Earth's atmosphere, where some is absorbed and re-radiated as longwave radiation. This longwave radiation is what is emitted back out into space.
conduction because there is more heat in space then there is in earth
Solar radiation leaves Earth's atmosphere through a process called reflection and absorption. Some of the radiation is reflected back into space by clouds, gases, and particles in the atmosphere. The remaining radiation is absorbed by the surface of the Earth, where it is converted into heat energy.
The energy exchange between space, the atmosphere, and Earth's surface produces a balance of incoming solar radiation and outgoing thermal radiation. Solar energy is absorbed by the Earth's surface, which then emits thermal radiation back into the atmosphere. Greenhouse gases in the atmosphere trap some of this thermal radiation, leading to the warming of the Earth's surface.
The radiation that Earth receives from the sun can be absorbed by the atmosphere, reflected back into space, or absorbed by the Earth's surface and converted into heat energy.
If a telesscope is in space it is not affected by the earths atmosphere so you get a better clearer more refined image. Space is colder so it is easier to pick up infrared radiation from other galixies.
About 30% of the sun's radiation is reflected back into space by the Earth's surface, clouds, and atmosphere. This reflection is known as albedo and helps regulate the Earth's temperature.
