Detailed explanation-1: -The North Pole and South Pole move in and out of sunlight as the Earth orbits the Sun. At the June solstice, the North Pole is pointed toward the Sun. No matter how much the Earth rotates, the Sun never appears to set, producing the phenomenon of the Midnight Sun.
Detailed explanation-2: -As it moves around the sun, the tilted axis means that at times part of the Earth will be closer to the sun than others. It’s also why summer occurs at different times of the year in the north and south hemispheres.
Detailed explanation-3: -The polar night is caused by the rotation of the earth in relation to the position of the sun. The earth rotates on a titled axis of around 23.5 degrees. As a result of this axial tilt, there are periods of the year where the Arctic Circle and the Antarctic Circle are either completely exposed or obscured from the sun.
