Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The ozone layer is damaged by
A
CFCs
B
Increase in greenhouse gases
C
Increased global temperatures
D
Sulfuric and nitric acids
Explanation: 

Detailed explanation-1: -Gaseous CFCs can deplete the ozone layer when they slowly rise into the stratosphere, are broken down by strong ultraviolet radiation, release chlorine atoms, and then react with ozone molecules. See Ozone Depleting Substance.)

Detailed explanation-2: -Chlorine-chlorine is a toxic chemical exerted from Chlorofluorocarbon. It contributes a major portion in depleting the ozone layer and also causing various health problems in human beings and animals.

Detailed explanation-3: -What is Ozone Layer Depletion? Ozone layer depletion is the thinning of the ozone layer present in the upper atmosphere. This happens when the chlorine and bromine atoms in the atmosphere come in contact with ozone and destroy the ozone molecules. One chlorine can destroy 100, 000 molecules of ozone.

Detailed explanation-4: -The higher the number, the more damage a chemical can cause to the ozone layer. Bromotrifluoromethane (halon‑1301) has an ozone depleting potential of 10.0. Carbon dioxide (CO2), a naturally occurring greenhouse gas, has an ozone depleting potential of 0.
