Given below are two statements, an Assertion (A) and a Reason (R). Choose the correct answer.
Assertion (A):According to IIT-Bombay studies, smog holes are fog burn-offs taking place in the middle of the morning hours, and the temperature within cities is warmer than the surrounding rural areas.
Reason (R):The holes, as big as cities, are the result of the urban heat island effect.
ABoth (A) and (R) are true and (R) is the correct explanation of (A) ✓ Correct
BBoth (A) and (R) are true but (R) is not the correct explanation of (A)
C(A) is true, but (R) is false
D(A) is false, but (R) is true
Correct answer: (A) Both (A) and (R) are true and (R) is the correct explanation of (A)
Explanation
Both the assertion and the reason are true, and the reason explains the assertion.
The assertion describes smog holes, per IIT Bombay studies, as mid-morning fog burn-offs, with city temperatures higher than the surrounding countryside.
The reason states that these city-sized holes result from the urban heat island effect.
Because cities trap and release more heat, the warmer air clears the fog faster and forms the holes described.
The reason thus supplies the heating cause behind the assertion's observation.
Concrete, asphalt and reduced greenery are the main drivers of the urban heat island.
