What substance can damage the ozone layer?

Answer 1

Chlorofluorocarbons (CFCs) and the chlorine that they release are causing the damage to the ozone layer, and the extreme thinning at the poles that are called "holes".

Ozone is a protective layer in the upper atmosphere. It is formed, when oxygen molecules absorb short wavelength ultra violet radiations from the sun. Ozone is mostly destroyed by free radicals in the atmosphere.

When compounds like CFCs (chlorofluorocarbons) and other halocarbons are released, they are dissociated by sunlight into chloride radicals. These radicals attack ozone, thereby decreasing its concentration. This results in a thinning of the ozone layer, and in polar regions, a hole.

The holes occur at the poles, and usually in Antarctica because of the extreme cold. During the winter polar stratospheric clouds form which are able to convert gases in the atmosphere into Cl (chlorine) and ClO (chlorine monoxide). When the sun arrives at the end of winter, that is the trigger to begin. This is why the hole is largest in spring.

Answer 2

Chlorofluorocarbons (CFCs) and halons are substances that can damage the ozone layer. When released into the atmosphere, these chemicals break down ozone molecules, leading to the depletion of the ozone layer.

Answer 4

CFC's are blamed for the hole in the ozone layer. They react with ozone present in atmosphere and deplete it.

Answer 5

Substances that can deplete ozone are in abundance. But one of them is CFC.

Answer 6

CFC gases which are pollutants are responsible for the depletion of ozone layer. CFC convert ozone to oxygen and make it useless for the absorption of UV radiation.

Answer 7

The ozone hole is caused by CFC's. These are released by humans through various artificial sources.

Answer 8

A hole in the ozone layer is caused by the CFC's. These CFC's allow the depletion of ozone by it's destruction.

Answer 9

CFCs (chlorofluorocarbons).

Answer 10

Chlorofluorocarbons (CFCs)
