UGC NET Questions (Paper – 1)

Statements A, B, C, D and F are correct: UHIs make cities warmer than rural areas; built surfaces and waste heat intensify warming; greening/cool roofs mitigate; and UHI is often stronger at night. Statement E is false because UHIs increase cooling demand and heat stress, affecting health. Hence, the correct combination is A, B, C, D and F only.

Option A:
Option A is incorrect as it omits F and therefore misses the well-known feature that UHI effects are often especially pronounced at night.

Option B:
Option B is correct because it includes all true statements and excludes E, which wrongly denies energy-demand and health implications.

Option C:
Option C is incorrect since it includes E, which is false.

Option D:
Option D is incorrect because it omits B, so it underplays the key role of built-up surfaces like concrete/asphalt in UHI formation.
