Question

Quizplus · Accepted Answer

Winter cold is caused by a combination of factors, including limited insolation and shorter daylight periods. Insolation refers to the amount of solar radiation that reaches a given area, and during winter, the sun's rays are angled more obliquely, so less radiation reaches the Earth's surface. Additionally, with shorter daylight periods, there is less time for the sun's rays to heat the ground, leading to colder temperatures. Therefore, winter cold is a manifestation of limited insolation and the brevity of the daylight period.
