Question

Accepted Answer

The correct option is 4:
The phenomenon known as the "Midnight Sun" occurs during the summer months in regions located within the polar circles, where the Sun remains visible for 24 hours a day. The Arctic Circle (approximately 66.5° N latitude) marks the southernmost limit of this phenomenon in the Northern Hemisphere. Any location situated north of the Arctic Circle experiences at least one day per year of continuous daylight. This happens because, during the summer solstice, the Earth's axial tilt causes the North Pole to be tilted towards the Sun, meaning areas beyond the Arctic Circle receive continuous solar radiation as the Earth rotates, giving rise to the name "The Land of the Midnight Sun."

The incorrect option is 1:
The Tropic of Cancer (23.5° N) is located in the equatorial zone, far south of the required latitude for the Midnight Sun phenomenon. Countries along this line experience conventional day and night cycles throughout the year. At the Tropic of Cancer, the Sun is directly overhead only once a year, during the summer solstice, but this location does not experience 24 hours of continuous sunlight at any point. For the Midnight Sun to occur, a location must be positioned beyond the polar circle, where the tilt of the Earth's axis keeps the sun above the horizon during the rotation.

The incorrect option is 2:
The Tropic of Capricorn (23.5° S) is the equivalent line of latitude in the Southern Hemisphere. While this region experiences summer months, it is far removed from the necessary latitudes (polar circles) for the Midnight Sun. This area only experiences the Midnight Sun's counterpart, the "Polar Day," in the winter of the Northern Hemisphere, but only for locations south of the Antarctic Circle, not the Tropic of Capricorn. Areas along the Tropic of Capricorn, like those along the Tropic of Cancer, exhibit standard day and night cycles.

The incorrect option is 3:
The Equator (0° latitude) experiences the least variation in day length throughout the entire year, with approximately 12 hours of daylight and 12 hours of night every single day. The concept of the Midnight Sun, which requires continuous daylight, is physically impossible at the Equator because this region is not affected by the extreme solar angles caused by the Earth's axial tilt. To find the Midnight Sun, one must travel towards the poles, not the Equator, which is the zone of lowest seasonal contrast.
