Which gas prevents damaging ultraviolet radiation from the sun from reaching earths surface?
Ozone
How does the ozone layer reduces the amount of ultraviolet radiation that reaches earths surface?
Ozone layer contains ozone molecules in abundance. These molecules decompose themselves to absorb ozone.
Why are there are almost no extrusive ultra basic rocks in earths crust?
There are almost no extrusive rocks on the earths surface because they are all under the earths surface. They are mainly lower than the earths 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.
Most of earths incoming ultraviolet radiation is absorbed by what?
The atmosphere and especially the ozone layer
How does the ozone layer reduce the amount of ultraviolet radiation that reaches earths surface?
Ozone is (relatively) opaque to ultraviolet light.
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.
Which gas prevents damaging ultraviolet radiation from the sun from reaching earths surface?
Ozone
How does the earths atmosphere protect organisms on the surface from the exposure to ultraviolet light?
The Earth's ozone layer blocks the ultraviolet light and protects the living organisms from the harmful UV rays. If it didn't, then everyone would burn up, we wouldn't be living, Earth would just be a rock floating through space.
What is blocked from reaching the earths surface by the ozone layer?
commonly 'sunlight', but more specifically UltraViolet 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.
What igneous rock formed from lava have a fine?
Volcanic (Extrusive) igneous rock, which are formed by lava that comes out of the earths crust, then cools and solidifies rapidly on the earths surface due to exposure to the environmental atmosphere.
Most of earths incoming is absorbed by ozone?
Ultraviolet light.
How does the ozone layer reduces the amount of ultraviolet radiation that reaches earths surface?
Ozone layer contains ozone molecules in abundance. These molecules decompose themselves to absorb ozone.
What percent of the earths surface is the US?
100
Why doesn't the ultraviolet radiation from the sun reach the ground?
It does, but in very small amounts because it is absorbed by Earths atmosphere. The ozonosphere blocks most of the UV radiation from striking the surface of earth.
How much of earths oceans cover earths surface?
70% or 80% of water covers the earths surface
