Question

What is meant by Ozone layer depletion?

Answer 1

1. Ozone layer depletion occurs when the upper atmosphere's ozone layer thins out.
2. Chlorine and bromine atoms in the atmosphere react with ozone molecules, destroying them.
3. Ozone layer depletion harms the absorption of UV photons from the sun.
4. The ozone layer acts as a protective barrier by absorbing harmful radiation. However, depletion provides direct and unfiltered access to UV radiation on the Earth's surface.
