In One Glance
Earth experiences day and night due to its rotation on its axis, which takes about 24 hours. When a location on Earth faces the Sun, it receives sunlight and it is daytime. As Earth rotates, that location turns away from the Sun and enters Earth’s shadow, creating nighttime. This cycle repeats consistently and also influences daily routines and sleep patterns. The story frames the rotation as a calm, reliable rhythm.
