Why We Have Seasons

Earth travels around the Sun once a year, and it is tilted, always leaning the same way. So for part of the year the top half of Earth leans toward the Sun and has summer, and later the bottom half has its turn.

In the picture

  1. Earth’s tilted axis: it always points the same way in space
  2. Northern half leaning toward the Sun: summer in the north
  3. Southern half leaning toward the Sun: summer in the south

Examples

  • When it is summer in Europe in July, it is winter in Australia.
  • In summer the Sun climbs high in the sky and the days are long, so you can play outside until late.
