Rotation
The movement of Earth spinning on its imaginary axis.
What is rotation?
The movement of Earth traveling in an orbit around the sun.
What is revolution?
Another common scientific name for lines of latitude.
What are parallels?
Another common scientific name for lines of longitude.
What are meridians?
