     • The part of the Earth that is facing the Sun has the Sun’s light shining on it and has daytime. The part of the Earth facing away from the Sun is in darkness and has night time. So when it is day time we are facing towards the Sun but as the Earth spins and we turn away from the Sun, we move into night time.

   Why do we have day and night?

   • As the Earth spins, the sun always shines on one side which gives it sunlight. When you’re facing the sun, it’s daytime. But when you’re on the part of the Earth that’s away from the sun, it’s nighttime. So, we have day and night because of the Earth’s rotation. And that line that separates day from night is the terminator line.

   How do days and nights change?

   • The changing lengths of days and nights depends on where you are on Earth and the time of year. Also, daylight hours are affected by the tilt of the Earth's axis and its path around the sun. A solar day, 24 hours, is the time it takes for the Earth to rotate exactly once so that the sun appears at the same place in the sky the next day.

   What is a solar day?

   • A solar day, 24 hours, is the time it takes for the Earth to rotate exactly once so that the sun appears at the same place in the sky the next day. However, the Earth is also moving around the sun, and this movement makes measuring the day somewhat complicated.

   Mar 9, 2018 · The change between day and night is caused by the rotation of the Earth on its axis. If the Earth did not rotate as it does, the day/night cycle would be very different or possibly even nonexistent. The changing lengths of days and nights depends on where you are on Earth and the time of year.

   When where you are is pointed toward the Sun, it is day. Then the Earth rotates you away from the Sun, and it is night. Think about this! So, how fast does the Earth have to rotate in order to make one complete spin in 24 hours? At the equator, the Earth is rotating at a speed of about about 2200 kilometers per hour.
