What is TRUE about the North and South Poles? Select all that apply.
Romashka [77]

The poles never get any direct sunlight.

They both get the same amount of sunlight.

  • Because they receive no direct sunshine, the Arctic (North Pole) and Antarctic (South Pole) are both chilly.
  • Even at the height of summer, the Sun is low on the horizon. The Sun doesn't rise at all for several months during the winter since it is so deep below the horizon hence poles don't have equal amounts of sunlight and darkness.
  • The poles receive less energy and heat from the sun because of the tilt of the earth and its orbit around the sun. There are just two polar seasons as a result: summer and winter.
  • The tilt of the Earth's axis causes the Poles to experience around six months of day and six months of night.
  • Due to this tilt, each Pole spends roughly six months angled both toward and away from the Sun. The North Pole experiences six months of nonstop daylight when it is inclined toward the Sun.
  • In the winter, the Sun sets for extended periods of time since it is so deep below the horizon. Therefore, the days are chilly and dark, much like the nights. The South Pole and North Pole receive the same amount of sunshine despite being "polar opposites."
