Axis
An imaginary line which runs through both
poles of a planet.
Rotation of the Earth
The Earth is spinning upon a central axis.
The Earth's axis is tipped over about 23.5° from the vertical.
The Earth rotates around once in 24 hours.
Direction of the Rotation
In which direction does the earth rotate?
Revolution of the Earth
The earth revolves around the sun. The orbit is elliptic. The Earth's tilt stays constant. The Earth completes one revolution in 365 days.
