How does the ozone layer reduce the amount of ultraviolet radiation that reaches earths surface?
Ozone is (relatively) opaque to ultraviolet light.
The lower atmosphere is directly warmed from?
It's warmed from the surface. Shortwave radiation passes through the atmosphere, or at least about half of it, where it reaches the ground and is absorbed. The ground re-emits it at a longer wavelength, thereby warming the lower atmosphere.
What kind of radiation passes through the atmosphere and reaches the earths surface?
highlight factors which show that heat from the sun does reach th earth surface by convection
What is the term for solar radiation that reaches the earth's surface?
The solar radiation that reaches the earths surface from the sun is called INSOLATION
What types of radiation can enter earths atmosphere?
The UV radiation that reaches the Earth’s surface is mostly UVA and some UVB. Almost half the daytime total of the more harmful UVB radiation is received between the hours of 10 a.m. and 4 p.m. Even on a cloudy day, you can be sunburned by UVB radiation.
What reaction occurs when ultraviolet radiation from the sun reaches the earth's atmosphere?
When UV reaches earth, it interacts with ozone. It both creates and depletes ozone.
Could the sun's radiation one day possibly give mars the power to hold life?
The problem with Mars is not that there is insufficient insolation but the lack of water and atmosphere. The thin atmosphere means that too much ultraviolet radiation reaches the surface (ultraviolet is extremely damaging to single-celled organisms); the problem with the lack of water should be obvious.
How does the ozone layer reduce the amount of ultraviolet radiation that reaches earths surface?
Ozone is (relatively) opaque to ultraviolet light.
How the ozone layer reduces the amount of ultraviolet radiation that reaches earth's surface?
The ozone layer acts as a shield in the Earth's atmosphere, absorbing much of the incoming ultraviolet (UV) radiation from the sun. This is due to the presence of ozone molecules, which have a natural ability to absorb UV radiation. By absorbing and scattering UV rays, the ozone layer prevents much of the harmful UV radiation from reaching the Earth's surface, protecting living organisms.
What happens as solar radiation travels towards earth?
Some is absorbed by molecules in the atmosphere (such as ultraviolet absorption by ozone), some is absorbed on the surface, and some is reflected by clouds or the surface back into space. The surface will re-radiate much of the absorbed solar radiation as infrared (thermal) radiation, and some of this is then absorbed by atmospheric gases such as carbon dioxide and methane.
What does the ozone layer do to ultraviolet layer?
The ozone depletion is increasing the amount of UV radiation that reaches the earth....
What is strong ultaviolet radiation reaches this country because the osone layer abpove it is thin ultraviolet radation damages the skin ans cause cancer?
UV are fatal rays of the sun. They are blocked by ozone in atmosphere.
What happens to most solar radiation when it reaches the surface of Earth what happens?
Most of the solar radiation is absorbed when it reaches the surface of the earth. Some of the solar radiation is also absorbed in the atmosphere.
Why doesn't all radiation directed at earth reaches the surface?
It is absorbed by the atmosphere
Solar radiation percentage reaches earth's surface in what wavelength?
They all do to some extent, but some wavelengths get through more easily than others. The Sun's radiation is primarily in the visible part of the radiation spectrum. A lot of that reaches the ground. A fair amount of the ultraviolet radiation is blocked by the ozone layer in our atmosphere. Some infrared radiation is absorbed by the atmosphere, but some also gets through to the Earth's surface. Radio wavelengths get through to the surface quite easily, which is why radio telescopes can be used on Earth.
What percentage of solar radiation reaches the earth and drives the hydro logic cycle?
About 50% of the incoming solar radiation reaches the surface of the planet. The rest is reflected or absorbed by the atmosphere & clouds, and a small portion is reflected by the oceans and land.
How does the energy from the sun reach the earth?
Waves of heat and light, called radiation, travel to earth.
