✓ Correct answer: b) 2 only
ExplanationThe annual range of temperature is the difference between the highest and lowest temperatures recorded in a particular place or region over the course of a year.Statement 1 is incorrect : The annual range of temperature (the difference between the highest and lowest average monthly temperatures) is generally smaller in the Pacific Ocean com- pared to the Atlantic Ocean.This is primarily due to the Pacif- ic’s larger size and greater thermal inertia.The vastness of the Pacific allows for more heat absorption and distribution, mod- erating temperature extremes.Atlantic’s relatively smaller size and its greater contact with Arctic waters leads to more pronounced seasonal temperature variations.Also the Atlantic Ocean is narrower and more enclosed, allowing for greater temperature variability.UPSC GS Paper-I PYQs 360Statement 2 is correct : The Northern Hemisphere has a greater annual range of temperature than the Southern Hemisphere.This is primarily due to the larger landmasses in the Northern Hemisphere, which heat up and cool down more quickly compared to the predominantly oc
