The correct Answer is:
### Step-by-Step Solution 1. **Understanding Ozone**: Ozone is a gas that exists in two primary locations in the Earth's atmosphere: the stratosphere (upper atmosphere) and the troposphere (lower atmosphere). 2. **Ozone in the Stratosphere**: Ozone in the stratosphere is beneficial as it forms the ozone layer, which protects the Earth from harmful ultraviolet (UV) radiation. This ozone is created through the interaction of UV radiation with molecular oxygen (O2). 3. **Ozone in the Troposphere**: In contrast, ozone that is formed at ground level in the troposphere is considered "bad ozone." This type of ozone is not emitted directly but is created by chemical reactions between volatile organic compounds (VOCs) and nitrogen oxides (NOx) in the presence of sunlight. 4. **Conclusion**: Therefore, "bad ozone" refers specifically to the ozone that is formed in the troposphere, which can have harmful effects on human health and the environment. ### Final Answer Bad ozone is defined as ozone formed in the troposphere, which is harmful to human health and the environment. ---
