The solar radiation least absorbed by the layers of the atmosphere before reaching Earth is?
visible light
How can human activity cause the increase in the ultraviolet light reaching the earth?
Ultraviolet radiation is unseen by the naked eye though the effect are often felt from sunburns to skin cancers. The Ultraviolet or UV radiation is the beneficial for needing vitamin D but over exposure can cause skin cancer.
Reflection and absorption by the atmosphere prevent some?
The sun's total energy package. There are about 1355 watts hitting each meter of atmosphere. Roughly 375 watts reach our planet. This amount varies greatly on weather conditions. Water vapor (clouds) provide most of the feedback loop.It is believed that man's contribution of 0.28% of the total green houses gases may have some affect on the current warming. Science suggests (and data supports) that this may well not be the issue. While man has been steadily increasing his contribution of CO2 to the atmosphere (now reaching 6% of total CO2 production and 0.28% of total GHG) we are seeing a steady decline in temperature worldwide. The crest seems to have been in 1998. The start point of this warming was about 6000 years ago. Of the 11 degrees (C) of warming we have verified, only 0.2 has occurred since man started using fuel.Reflection and absorption by the atmosphere prevent some solar radiation from reaching the earth's surface.
What absorbs a portion of a radiation from the sun preventing it from reaching the earth's surface?
Generically the atmosphere absorbs portions of the Sun's radiation. In particular the Ozone layer absorbs a lot of UV radiations and of course water in the atmosphere (clouds) can blot out the Sun entirely.
What is the difference between direct and indirect global warming potential?
They are two types of radiation 1. Direct radiation 2.Diffused radiation The solar radiation reaching the surface of atmosphere of earth is known as extra terrestrial radiation. In which some part of radiation directly enters the earth atmosphere and some part enters the earth atmosphere by reflecting from clouds, gases , aerosols etc., The radiation which directly enters the earth atmosphere is known as "Direct radiation" The radiation which enters the earth atmosphere by reflecting from clouds, gases, aerosols is known as diffused radiation. In materiology the sum of both Direct radiation and Diffused radiation is called total radiation.
What the most ultraviolet radiation is blocked from reaching earths surface by what substance found in the atmosphere?
Ozone in the atmosphere blocks most of the UV radiation from the Sun... Without it's protection - the planet would overheat.
Which gas prevents damaging ultraviolet radiation from the sun from reaching earths surface?
Ozone
Which type of electromagnetic radiation does the ozone layer prevent from reaching the surface of the earth?
Ultraviolet waves
Is the greenhouse effect the same as ozone depletion?
No, they are different. Ozone depletion results in more ultraviolet (short wave) radiation reaching earth's surface. The greenhouse effect results in more infrared (long wave) radiation being absorbed by the atmosphere.
What is blocked from reaching the earths surface by the ozone layer?
commonly 'sunlight', but more specifically UltraViolet radiation
What controls the amount of uv light that enters the atmosphere?
There are several factors that control the amount of UV light that enters the atmosphere. The main factors include the ozone layer and weather conditions.
Which gas in the atmosphere protect life from the sun's harmful?
The gas in the atmosphere that protects life from the sun's harmful ultraviolet (UV) radiation is ozone (O3). The ozone layer is located in the stratosphere and acts as a shield, absorbing most of the UV radiation and preventing it from reaching the Earth's surface. Without ozone, excessive UV radiation would have damaging effects on living organisms.
The solar radiation least absorbed by the layers of the atmosphere before reaching Earth is?
visible light
What are facts about sunscreen?
Sunscreens are products combining several ingredients that help prevent the sun's ultraviolet (UV) radiation from reaching the skin. Two types of ultraviolet radiation, UVA and UVB, damage the skin, age it prematurely, and increase your risk of skin cancer.
The danger of ultraviolet radiation?
It is simple the ozone layer pertects some of the ultraviolet radiation that comes from the sun if you are exposed to much of the sun you can get skin cancer that is the danger of ultraviolet radiation
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.
Would uv radiation decrease if the earth's atmosphere vanished?
It would increase, because there would be nothing to absorb it in the atmosphere before reaching the ground.
