Solution
During the solstices, at the Equator, the Sun’s rays are nearly vertical, resulting in equal day and night. As you move towards the poles, the Sun's rays become more slanted, leading to shorter days and longer nights during the winter solstice and longer days during the summer solstice. At the poles, there are periods of 24-hour daylight or polar night depending on the season.
