Why are the North and South Poles colder than the equator? A. C. B. D.
A
They receive less direct sunlight
B
There is no temperature difference
C
They receive more direct sunlight
D
The equator is colder
Explanation: 

Detailed explanation-1: -Both the Arctic (North Pole) and the Antarctic (South Pole) are very cold because they get very little direct sunlight. The Sun is always low on the horizon, even in the middle of summer. In winter, the Sun is so far below the horizon that it doesn’t come up at all for months at a time.

Detailed explanation-2: -The main reason that Antarctica is colder than the Arctic is that Antarctica is a landmass surrounded by ocean, and the Arctic is an ocean surrounded by landmasses. Antarctica also has a much higher average elevation than the Arctic, and the Antarctic Ice Sheet is bigger and thicker than the ice in the Arctic.

Detailed explanation-3: -The angle of sunlight hitting the equator is more direct than it is at the poles, so the poles receive less direct sunlight.

Detailed explanation-4: -Because the Earth is a sphere, the Sun heats equatorial regions more than polar regions. The atmosphere and ocean work non-stop to even out solar heating imbalances through evaporation of surface water, convection, rainfall, winds, and ocean circulation.
