How our atmosphere blocks a lot of radiation?

The Earth's atmosphere acts as a protective shield by absorbing and scattering various types of harmful radiation from the sun, such as ultraviolet (UV) and cosmic rays. The ozone layer, located in the stratosphere, specifically absorbs the majority of the sun's harmful UV radiation, preventing it from reaching the surface. Additionally, atmospheric gases and particles scatter and reflect some incoming radiation, reducing its intensity. This protective mechanism is crucial for maintaining life on Earth by limiting exposure to radiation that could cause damage to living organisms.
