Final answer:
The North is sometimes called the Land of the Midnight Sun because during summer in the Northern Hemisphere, the North Pole is illuminated by the Sun for 24 hours per day. This occurs due to the tilt of the Earth's axis.
Step-by-step explanation:
Regions north of the Arctic Circle are known as the "land of the midnight Sun" because during summer in the Northern Hemisphere, the North Pole is illuminated by the Sun for 24 hours per day. This phenomenon occurs due to the tilt of the Earth's axis. As Earth turns on its axis, the North Pole is continuously exposed to the Sun, resulting in extended daylight.
