Question

How are
we protected from uv rays​

Answer 1

Hey mate,

A layer of ozone(O3) protects us from UV rays

When UV rays come it breaks the Oxygen molecule (O2) into single oxygen i.e- O+O

And the single oxygen reacts with other oxygen molecule to form the ozone

O+O2=O3

And this process continues and the ozone forms a protective layer .

Hope it helps
