What is the name for Earth's spin on its axis that creates day and night?

• A. Rotation
• B. Revolution
• C. Orbit
• D. Tilt

Answer: (A)

Rotation is the spin of Earth on its own axis. As the planet turns, different locations move into and out of the Sun’s light, which creates day when a place faces the Sun and night when it faces away. This spinning is about an internal axis, not about traveling around the Sun. The orbit around the Sun is called revolution, and the tilt of Earth’s axis influences seasons, not the daily cycle. So the name for Earth's spin on its axis that creates day and night is rotation.
