What causes the seasons to change?

  • The seasons are caused by the way the Earth is tilted.
  • The parts of the Earth that are tilted towards the Sun get more of the Sun's heat and light.
  • The parts of the world which are tilted away get less of the Sun's heat and light.
  • The Earth takes a full year (365 days) to around the Sun.
  • As the Earth travels around the Sun, places that are tilted towards the Sun change. These changes are known as seasons.
  • The four seasons are: spring, summer, autumn and winter.
