What is day? What is night?
Let's explore the differences and similarities!
Why does daytime happen? Why does nighttime happen?
But how does it keep changing from day to night? Well, whenever the Earth faces the Sun, it is daytime; whenever the Earth faces away from the Sun, it is nighttime. This occurs because the Earth rotates within its axis, or goes around itself, which takes 24 hours to complete (1 full day). As a result, throughout the 24 hours of our day, we are able to see the cycle of day and night.
