Concept Explanation
 

Day and Night

Varying lengths of day and night: The lengths of days and nights can be very different, even at the same time of year. This variation is due to the inclination of the earth’s axis. For half the year, the Northern Hemisphere faces the Sun, while for the next six months; the Southern Hemisphere faces the Sun. A larger part of the hemisphere that faces the Sun gets longer days and shorter nights. At the equator, the days and nights are of equal length.
