Why does the northern hemisphere get 24 hours of daylight and 24 hours of darkness in the winter?

The northern hemisphere experiences 24 hours of daylight and darkness due to the axial tilt of the Earth. During the winter solstice, the North Pole is tilted away from the Sun, resulting in continuous darkness in areas above the Arctic Circle. Conversely, during the summer solstice, the North Pole is tilted toward the Sun, leading to 24 hours of daylight. This phenomenon is a result of the Earth's rotation and its axial inclination relative to its orbit around the Sun.
