Day and Night

The Sun always lights one half of the Earth. As the Earth spins, places move into the light (day) and out of it (night).

Key ideas

  • The Earth spins on its axis once in about 24 hours.
  • The half facing the Sun has day; the other half has night.
  • The Sun seems to rise and set because the Earth turns, not because the Sun moves around us.
