* Earth's Rotation: The Earth constantly rotates on its axis, completing one full rotation roughly every 24 hours. This is what causes day and night. So, at any given moment, half of the Earth is facing the sun (daytime) while the other half is facing away (nighttime).
* Earth's Orbit: The Earth orbits the sun in an elliptical path. This means that Earth is not always the same distance from the sun, but it's always rotating.
Instead of a specific term, we use the following:
* Nighttime: This describes the period when a specific location on Earth is facing away from the sun.
* The night side of Earth: This refers to the hemisphere of Earth that is facing away from the sun at any given time.
