Four Seasons

Most places on Earth experience four seasons every year. These are spring, summer, fall (or autumn) and winter. Here we are going to find out why we have different seasons.

The seasons are caused by a combination of things.
  • The Earth is tilted as it moves around the sun.
  • Direct sunlight produces more heat than indirect light.
  • The Earth moves around the sun in a way you may not expect.

We will look at each of these in turn, and then see how all three, together produce the seasons.
