"Bad ozone" is found in

Options

A. trohosphere
B. stratosphere
C. ionosphere
D. exosphere

Answer

**Step-by-Step Solution:**

1. **Understanding Ozone Layers**: Ozone exists in different layers of the Earth's atmosphere, primarily in the troposphere and stratosphere.

2. **Identifying "Bad Ozone"**: The term "bad ozone" refers to ozone that is found in the lower atmosphere, specifically in the troposphere. This ozone is not emitted directly but is formed by chemical reactions between volatile organic compounds (VOCs) and nitrogen oxides (NOx) in the presence of sunlight.

3. **Effects of Bad Ozone**: Bad ozone is harmful to human health, plants, and animals. It can cause respiratory problems, reduce lung function, and harm ecosystems.

4. **Good Ozone vs. Bad Ozone**: In contrast, "good ozone" is found in the stratosphere, where it forms the ozone layer that protects life on Earth from harmful ultraviolet (UV) radiation.

5. **Conclusion**: Based on the information provided, "bad ozone" is found in the troposphere.

**Final Answer**: Bad ozone is found in the troposphere.
