What effect do oblique sun rays and longer nights create together in winter?

Answer and explanation

Correct answer: They cool the surface

In winter, the Sun’s rays reach the surface at a more slanting angle, so the same solar energy is spread over a larger area. Winter nights are also longer, giving the ground more time to lose heat. Together, these conditions reduce the heating of the land and lower surface temperatures. Therefore, option A, “They cool the surface,” is correct.

The other choices describe different weather phenomena. Loo is a hot, dry wind of the warm season, mango showers are pre-monsoon rains, and the burst of monsoon occurs when the monsoon begins. None is caused by weak winter heating and long nights. The key reasoning is to connect the angle and duration of sunlight with the heat received and lost by the surface.
