Practice questions

Q1Consider the following statements about the unusual ozone layer reported over the North Bay of Bengal: 1. Scientists discovered an unusually thick ozone layer about 21 to 23 kilometres above the North Bay of Bengal. 2. The ozone layer normally reaches its maximum concentration at altitudes of about 15–20 km. Which of the statements given above is/are correct?

A 1 only

B 2 only

C Both 1 and 2

D Neither 1 nor 2

Explanation

Statement 1 is correct: the campaign found an unusually thick ozone layer about 21–23 km above the North Bay of Bengal. Statement 2 is incorrect: the release states that ozone normally reaches its maximum concentration at about 25–30 km, not 15–20 km.
