1. The ozone layer is primarily found in the stratosphere and it absorbs harmful ultraviolet (UV) radiation from the Sun.
2. Ozone holes are more commonly found over the Antarctic region than the Arctic region.
3. The main cause of ozone depletion is the emission of carbon dioxide (CO2) from industrial activities.

Which of the statements given above are correct?
(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2, and 3

ONLiNE UPSC · Accepted Answer

Statement 1 is correct: The ozone layer is located in the stratosphere (between 10&ndash;50 km altitude) and absorbs harmful UV radiation, protecting life on Earth.

Statement 2 is correct: Ozone holes are more common over Antarctica due to extremely cold temperatures and the formation of polar stratospheric clouds, which enhance ozone depletion.

Statement 3 is not correct: Carbon dioxide (CO2) is not responsible for ozone depletion. Instead, chlorofluorocarbons (CFCs), halons, and other ozone-depleting substances (ODS) are the primary causes.
