T6 Big Ideas Big Book Raise Your SciQ! Extreme Day and Night The length of day and night differs from season to season and from place to place on Earth. In places near the poles, such as Alaska, these differences are quite extreme. During the summer in Alaska, the sun may light the sky for 20 hours a day or longer. In the winter, the pattern reverses, and the sky is dark most of the time. At both the North and South Poles, the sun lights the sky for half of the year. Both day and night last 6 months each!
