What else can I help you with?
Which gas prevents damaging ultraviolet radiation from the sun from reaching earths surface?
Ozone
How does volcanic ash in Earths atomosphere affect solar radiation?
It blocks (some of) it from reaching the surface of the Earth.
What is blocked from reaching the earths surface by the ozone layer?
commonly 'sunlight', but more specifically UltraViolet radiation
What percent of the suns radiation is lost before reaching the earths surface?
Approximately 30% of the Sun's radiation is reflected back into space by clouds, atmospheric gases, and the Earth's surface. Additionally, about 20% is absorbed by the atmosphere, leaving around 50% of the Sun's radiation to reach the Earth's surface. This means that roughly 50% of the incoming solar radiation is lost before it reaches the ground.
When solar radiation enters the atmosphere most of the solar radiation is absorbed by the earths surface. However about 6 percent of the solar radiation is blank by the earths surface?
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.
What percent of the earths surface is the US?
100
How does albedo affect the behavior of solar radiation reaching earths surface?
Albedo refers to the reflectivity of a surface. Surfaces with high albedo reflect more solar radiation back into space, which can cool the Earth's surface and lower temperatures. Surfaces with low albedo absorb more solar radiation, leading to warming of the Earth's surface.
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.
What type of radiation is trapped on the earths surface by the green house effect?
Infrared radiation
What absorbs energy that is radiation from earths surface?
the greenhouse effect!
Why is the atmosphere needed on a planet?
Atmospheres have many different purposes, however the Earths atmosphere is vital to its existense as it prevents the suns harmful radiation from reaching the Earths surface. Moreover, from an enviromental standpoint the errosion by pollutants will eventually destroy the delicate atmosphere and the Earths protective barrier will be gone.
How does the presence of oxygen in our atmosphere help reduce the amount of ultraviolet radiation that reaches the earths surface?
Oxygen in the atmosphere helps to absorb and scatter incoming ultraviolet (UV) radiation from the sun. This process occurs in the stratosphere, where oxygen molecules break apart the incoming UV radiation. This absorption and scattering of UV radiation by oxygen prevent a large amount of harmful UV radiation from reaching the Earth's surface.
