Charged particles from the Sun will not reach the surface of the Earth because they are mostly deflected around it by the Earth's magnetic field (the magnetosphere), but where the particles are deflected towards the surface near the Earth's magnetic poles, they interact with the gas high in the atmosphere to form the Auroras and do not penetrate through to the surface.
Its the bio/atmosphere of the earth. It is currently getting weaker
Most of the UV radiation would be breached if there was no ozone. This is the protective layer.
Ozone layer
Ozone
Sorry, but your data is wrong. Nitrogen does reach the surface. Its 4/5 th of the atmosphere.
Ozone in the atmosphere blocks most of the UV radiation from the Sun... Without it's protection - the planet would overheat.
Infrared radiation
radiation & gravity
Ozone
commonly 'sunlight', but more specifically UltraViolet radiation
It blocks (some of) it from reaching the surface of the Earth.
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.

the answer is radiation
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
