Question

The ozone layer in our atmosphere protects us from the bad effects of:

• A. Carbon dioxide
• B. CFC's
• C. The sun's ultraviolet rays
• D. All of the above

Answer 1

The correct option is C The sun's ultraviolet rays

The ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (UVR) from the sun, protecting life on Earth from its potentially harmful effects. When the sky is clear, there is an inverse relationship between stratospheric ozone and solar UVR measured at the Earth’s surface. That is,the lower the ozone levels, the higher the solar UVR.

Hence, the correct option is $\text{C}$
