When earths surface is heated it radiates some of the energy back into the atmosphere as ultravioet radiation?

That's...rather unlikely...
Across the Electromagnetic Spectrum (Radio, Microwave, Infrared, Visible light, Ultraviolet, X-ray, and Gamma radiation), The higher you go in frequency (and the lower the wavelength), the higher the temperature must be to emit its respective radiation.
To emit ultraviolet rays, a body must at least be able to produce its own light source. Since Earth is not capable of that, we can rule out that it produces light waves from that heating.
Whether Earth can radiate UV radiation is debatable. The ozone layer, the protective shield hovering over us, reflects the great majority of UV back into space. A small amount pervades through this layer, and will show up, and some reflective surfaces like the ocean will reflect it. However, to say it radiates?
Additionally, UV radiation is not the cause of heating. Most people think that because UV radiation from an untampered source will always be accompanied by Infrared radiation (which is the actual cause of heating), so they simply associate UV rays and heat together. So UV rays do not heat up the atmosphere. They are reflected in moderate amounts, but they do not cause thermal fluctuations.

Wiki User
∙ 11y agoYes, of course. Basically, all the energy (or almost all of it) that the Earth absorbs from the Sun must be radiated back into space at some moment.
Wiki User
∙ 10y agoFalse. The heat radiation from Earth will go out as infrared, not as ultraviolet.
Wiki User
∙ 8y agoNot as ultraviolet; the radiation is emitted as infrared radiation.
Wiki User
∙ 12y agoNo, It radiates Infrared Radiation.
Wiki User
∙ 9y agoYes. That's why it gets cold at night.

What are greenhouse gases referred to?
The greenhouse effect refers to the change in the thermal equilibrium temperature of a planet or moon by the presence of an atmosphere containing gas that absorbs and emits infrared radiation. Greenhouse gases, which include water vapor, carbon dioxide and methane, warm the atmosphere by efficiently absorbing thermal infrared radiation emitted by the Earth's surface, by the atmosphere itself, and by clouds. As a result of its warmth, the atmosphere also radiates thermal infrared in all directions, including downward to the Earth's surface. Thus, greenhouse gases trap heat within the surface-troposphere system.
What factors in an atmosphere seem to have the greatest effect on the amount of radiation received from the sun?
The ozone layer has the greatest effect on the amount of ultraviolet radiation received at the earth's surface from the Sun. Cloud formation and atmospheric thickness, in combination with solar angle, have the greatest effect on the amount of visible and infrared radiation received at the earth's surface from the sun
How is air warmed?
The sun, originally, but the sun actually heats the earth, and warm air rises from the surface of the earth and is trapped by greenhouse gases in the atmosphere. This is mostly how the air gets warm.
What does the term greenhouse effect mean?
Green house effect is a process in atmospheric physics that traps heat in the Earth's atmosphere. It is the result of physical interaction between components of the atmosphere (greenhouse gases) and incoming sunlight. It is not a layer of carbon dioxide in the sky that reflects heat back down as it radiates from the Earth's surface. Heat is absorbed by the carbon dioxide all through the atmosphere and the warmer gas "shares" its heat with all the atmospheric gases increasing the average atmospheric temperature.
Is Colorado high in cosmic radiation?
There are two factors which determine the relative level of cosmic radiation at different points on the earth's surface. First, because the earth's magnetic field deflects the charged particles in cosmic radiation toward the magnetic poles, cosmic radiation levels are generally higher the closer you are to a magnetic pole, i.e., the higher your geomagnetic latitude. Second, since the earth's atmosphere provides physical shielding from cosmic radiation, cosmic radiation levels are generally higher at higher altitudes where there is less atmosphere between you and the vacuum of space. As it turns out, the impact of differences in altitude is much greater than the impact of differences in geomagnetic latitude. Because Colorado has a high average elevation, cosmic radiation is generally higher there than at other locations with lower altitudes.
When Earths surface is heated it radiates some of the energy back into the atmosphere as?
When Earths surface is heated it radiates some of the energy back into the atmosphere as "Infrared Radiation."
When earths surface is heated it radiates most of the energy back into the atmosphere as ultraviolet radiation?
Not as ultraviolet; the radiation is emitted as infrared radiation.
If Earths surface is heated does it radiate most of the energy back into the atmosphere as ultraviolet radiation?
No. It radiates most energy back as infarred radiation.
How radiation from the sun penetrates the atmosphere by heating the air?
Solar radiation penetrates most of the atmosphere and is mostly absorbed by earth's surface. The surface then radiates energy of a different wavelength (in the thermal infrared part of the spectrum, which we perceive as heat) back to the atmosphere, heating the lower atmosphere.
What heats earths atmosphere?
The sun heats the atmosphere. Solar radiation largely passes through the atmosphere and warms the surface of the earth. The earth then radiates heat up into the lower levels of the atmosphere where greenhouse gases warm. The warmed greenhouse gases then continue to radiate heat in all directions warming the atmosphere and again the earth's surface.
How is air heated by the Earth's surface one word?
In one word... radiation. More specifically... the sun heats the Earth's surface, and the absorbed heat radiates back into the atmosphere.
How is treat transferred away from the surface of the moon if the moon has no atmosphere?
By radiation. The moon radiates electromagnetic energy, as does just about anything warmer than absolute zero.
Carbon dioxide traps shortwave radiation and re-radiates it?
Carbon dioxide mainly has an effect on longwave radiation. It absorbs longwave radiation and re-radiates it, some of it back downwards. This means carbon dioxide increases the amount of radiation going back down to the surface, and the surface has to warm up to compensate.
The earths surface transfers heat to the atmosphere primarily by?
the answer is radiation
When does the earth emit terrestrial radiation?
Terrestrial radiation refers to heat emitted from the earth's atmosphere and surface.
What form is radiation emitted from the earth's surface back into the atmosphere?
Heat rises from the surface of the earth in the form of infra-red radiation.
Is it true when heated Earths surface radiates some of the energy back into the atmosphere as infrared radiation?
Yes, of course. Basically, all the energy (or almost all of it) that the Earth absorbs from the Sun must be radiated back into space at some moment.
