The correct Answer is:
To determine the thickness of ozone in a column of air from the ground to the top of the atmosphere, we follow these steps: ### Step-by-Step Solution: 1. **Understanding Ozone Measurement**: Ozone thickness is a measure of how much ozone is present in a vertical column of the atmosphere. It is important to know how this thickness is quantified. 2. **Identifying the Correct Unit**: The thickness of ozone is specifically measured in a unit that quantifies the amount of ozone in a column of air. 3. **Recognizing the Dobson Unit**: The standard unit used for measuring the thickness of ozone is the Dobson Unit (DU). One Dobson Unit corresponds to a layer of ozone that would be 0.01 millimeters thick at standard temperature and pressure. 4. **Conclusion**: Therefore, the thickness of ozone in a column of air from the ground to the top of the atmosphere is measured in terms of Dobson Units. ### Final Answer: The thickness of ozone in a column of air from the ground to the top of the atmosphere is measured in terms of **Dobson Units**. ---
