KIDS TRIVIA

Detailed explanation-1: -During summer, they insulate the underground water and soil from the heat radiation from the sun, and from the general hotter atmosphere, hence underground water is colder. In winter, they again act as insulating layer and prevent the heat from underground to escape into the cold outside air.

Detailed explanation-2: -When the northern hemisphere is pointed toward the sun, sunlight hits more directly, and it warms up this part of the earth. In the winter, when the northern hemisphere is pointed away from the sun slightly, the sun’s rays come in at an angle and have less of an impact. This makes winter cold!
