The Ozone layer protects us from: (1) Cosmic rays (2) Ultra-Violet rays (3) Visible rays (4) Infrared rays
by

1 Answer

Answer :

(2) Ultra-Violet rays Explanation: The ozone layer refers to a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet (UN) radiation. It absorbs 97- 99% of the Sun's medium-frequency ultraviolet light (from about 200 nm to 315 nm wavelength), which otherwise would potentially damage exposed life forms near the surface.
