The ozone layer in our upper atmosphere.
It blocks the harmful UV rays. These are radiations of the sun.
Ozone (O3) forms from oxygen (O2) in the upper atmosphere and screens out most of the ultraviolet radiation from the Sun.
Ozone.
The shorter electromagnetic wavelengths are the more harmful. Shortwave ultraviolet is more harmful than long wave ultraviolet light. With even shorter wavelengths are gamma rays and x-rays which can cause genetic mutations and cell damage leading to death.
The most common one is skin cancer but the most publicised one is skin cancer, rare but possible if exposed to even low levels of UV light
The ozone layer high above the Earth blocks most of the ultraviolet (UV) light emitted by the Sun. This radiation is generally harmful to living things.
Most of the light in sunlight is ultraviolet light, also known as UV light/rays.
the lens is the most sensitive part of the eye. the retina can become damaged when there is an excessive ultraviolet light exposed.
Ultraviolet light.
If that will happen life on earth would be wiped out. Most ultraviolet light heading for earth would be blocked by the ozone layer.
UV-C is the most harmful type of UV ray. It is the one absorbed by the ozone.
Most of it is absorbed. UV is the harmful radiation of the sun.
