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.
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
Clouds are not a form of protection. They dim the sunlight we receive but do not filter UV radiation. They can and do reduce light and infra red radiation reaching the surface of the earth
It's as a result of the light passing though our atmosphere - and the same reason that the sky is blue !
Some atmosphere from the terminator pours over the horizon, and there might be a tiny bit of warmth from sunlight reflected off the lunar surface. However, essentially, the sun does not warm the atmosphere at night. This is why, on average, the atmosphere tends to cool all night long, reaching its coldest point just before sunrise.
Ozone
ozone
Ozone in the atmosphere blocks most of the UV radiation from the Sun... Without it's protection - the planet would overheat.
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.

Ultraviolet waves
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.
commonly 'sunlight', but more specifically UltraViolet radiation
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.
