See "What is the ozone layer?" in the "Related questions" section below.
Infrared radiation
radiation & gravity
The earth's magnetosphere acts as a shield to deflect harmful energies away.
Ozone
Ozone layer contains ozone molecules in abundance. These molecules decompose themselves to absorb ozone.
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.
Infrared radiation.
the answer is radiation
Ozone is (relatively) opaque to ultraviolet light.
Infrared radiation
the greenhouse effect!
Long-wave radiation and visible light.
The solar radiation that reaches the earths surface from the sun is called INSOLATION
radiation & gravity
Not as ultraviolet; the radiation is emitted as infrared radiation.
When Earths surface is heated it radiates some of the energy back into the atmosphere as "Infrared Radiation."
