Question

Explain the difference between rotation and revolution.

Answer 1

Rotation: Earth’s rotation is why we have day and night (it turns on its axis)

Revolution: Earth’s revolution is what we base our years after (the Earth revolving around the sun)

Answer 2

When an object turns around an internal axis (like the Earth turns around its axis) it is called a rotation. When an object circles an external axis (like the Earth circles the sun) it is called a revolution.
