Evaluate these statements regarding atmospheric layers: 1. Most weather phenomena occur in the stratosphere. 2. The ozone layer is primarily found in the troposphere. Which of the above is/are correct?
Neither 1 nor 2
Statement 1 – Incorrect. Almost all weather phenomena (clouds, rain, storms, thunder) occur in the troposphere, the lowest atmospheric layer (roughly 0–12 km), not the stratosphere. The stratosphere is largely stable and stratified, with very little vertical mixing.
Statement 2 – Incorrect. The ozone layer is primarily located in the lower stratosphere (roughly 15–35 km altitude), not in the troposphere. The two statements have effectively been swapped.
Both statements are wrong. Hence, the correct answer is Neither 1 nor 2.
