The correct Answer is:
To determine which statement is not correct regarding ozone and its effects, we can analyze each statement provided in the question. ### Step-by-Step Solution: 1. **Understanding the Greenhouse Effect**: - The greenhouse effect is a natural process where certain gases in the Earth's atmosphere trap heat, preventing it from escaping back into space. This process helps to maintain the Earth's temperature. - Common greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases. **Hint**: Remember that greenhouse gases are primarily responsible for trapping heat, not ozone. 2. **Evaluating the Statements**: - **Statement A**: "Ozone is responsible for the greenhouse effect." - This statement is incorrect. While ozone is a greenhouse gas, it is not a primary contributor to the greenhouse effect compared to CO2 and CH4. - **Statement B**: "Ozone can oxidize SO2 present in the atmosphere to SO3." - This statement is correct. Ozone can react with sulfur dioxide (SO2) in the atmosphere to form sulfur trioxide (SO3). - **Statement C**: "The ozone hole is thinning." - This statement is correct. The ozone layer has been depleting due to human-made chemicals, leading to a thinning of the ozone layer, often referred to as the ozone hole. - **Statement D**: "Ozone is present in the upper stratosphere." - This statement is also correct. The ozone layer is located in the stratosphere, which is above the troposphere. 3. **Identifying the Incorrect Statement**: - After evaluating all the statements, it is clear that **Statement A** is the only incorrect statement regarding ozone and its role in the greenhouse effect. ### Final Answer: The statement that is not correct is **Statement A**: "Ozone is responsible for the greenhouse effect." ---
