UPSC NDA-2 – 2015
Statement B is not correct. Temperatures in equatorial regions exhibit very little seasonal variation because the sun’s rays are always close to vertical throughout the year. Seasonal temperature changes are much more pronounced at higher latitudes due to the varying angle of sunlight and length of day/night.
This question tests knowledge of geographical factors influencing temperature distribution and variation across the globe.
Statement A is correct; average temperatures generally decrease with increasing latitude. Statement C is correct; large landmasses in high latitudes experience extreme cold winters due to continentality and long periods without sunlight. Statement D is correct; temperature generally decreases with increasing altitude due to the atmospheric lapse rate.
