Final answer:
The midnight sun lasts for varying periods of time at different latitudes due to the tilt of the Earth's axis and its orbit around the Sun.
Step-by-step explanation:
The midnight sun lasts for varying periods of time at different latitudes. In the Northern Hemisphere, the Arctic Circle experiences a 24-hour night during the summer solstice, while in the Southern Hemisphere, the Antarctic Circle has the midnight sun during the winter solstice. At latitude 23° S, called the Tropic of Capricorn, the Sun passes through the zenith at noon. This phenomenon is due to the tilt of the Earth's axis and its orbit around the Sun.
