Question

name two gases which deplete ozone layer​

Answer 1

Answer:

Hope these ans helps uh ❤

Explanation:

Chlorofluorocarbons (CFCs

Chlorofluorocarbons (CFCs) and other halogenated ozone depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion. The total amount of effective halogens (chlorine and bromine) in the stratosphere can be calculated and are known as the equivalent effective stratospheric chlorine (EESC).

Answer 2

Chloro Fluoro carbons and halons are two of the gases that deplete ozone layer.

Explanation:

• The ozone layer sits in the upper atmosphere and reduces the amount of harmful ultra violet radiation that reaches Earth from the sun.

• Ultraviolet radiation can have detrimental effects on both humans and the environment.

• A hole in the ozone layer surrounding the earth could have serious effects on human health and the environment.

• Ozone depleting substances are human made gases that destroy ozone once they reach the ozone layer.

• The depletion of the ozone layer is caused mainly by the increase in emissions of chlorine and bromine containing compounds like CFCs, halons, carbon tetrachloride, methyl chloroform and methyl bromide.

Halons

• Halons are halogenated  hydrocarbon gases originally developed to extinguish  fires.

• Halons are widely used to protect large computers, military hardware, and commercial aircraft engines.  

• Because of these uses, halons are often directly released  into the atmosphere.

Chloro Fluoro Carbon

• CFCs along with carbon tetrachloride and methyl chloroform, historically have been the most important chlorine containing gases that are emitted by human  activities and destroy stratospheric ozone.

• These and other chlorine-containing gases have been  used in many applications, including refrigeration, air conditioning, foam blowing, aerosol propellants, and cleaning of metals and electronic components.
