Question

Where are chlorofluorocarbons found?

1) In the atmosphere
2) In the oceans
3) In the soil
4) In the plants

Answer 1

Chlorofluorocarbons (CFCs) are found in the atmosphere. They contribute to the greenhouse effect and ozone depletion.

Step-by-step explanation:

Chlorofluorocarbons (CFCs) are found in the atmosphere. They contribute to the greenhouse effect in the lower atmosphere and diffuse into the stratosphere. In the stratosphere, they are broken down by ultraviolet (UV) radiation, releasing chlorine (Cl) atoms. These Cl atoms break down ozone molecules, leading to ozone depletion.
