Practice questions

Q1With reference to the North Bay of Bengal ozone enhancement reported by PIB, consider the following statements: 1. The enhanced ozone layer was observed only during daytime, indicating that sunlight-driven photochemical processes were its primary cause. 2. Researchers concluded that the unusual enhancement was mainly associated with the transport of ozone-rich air, followed by downward atmospheric motion and compression of the air mass. 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 incorrect: the enhanced layer was observed during both daytime and nighttime, suggesting photochemistry was unlikely to be the primary cause. Statement 2 is correct: researchers linked the enhancement mainly to transport of ozone-rich air, then downward motion and compression.
