Earth’s SpinningWe know the Earth orbits the Sun once a year.
But, the Earth also spins on its own invisible axis.
The Earth takes one day to spin around.1 day = 24 hours
When the Earth spins, half is in the Sun’s light (day) and half is in the Sun’s dark shadow
(night).
How long does it take for Earth to spin on its axis?
It takes one day. One day is 24 hours.
