Why do seasons change?

Seasons change because the axis of the earth is tilted by 23.5 degrees (from a line perpendicular to its orbit). As the earth moves around its orbit there is a time when it is tilted towards the sun and so receives a higher concentration of the sun's energy (summer) and a time when it is tilted away and receiving less energy (winter).

This also explains why it is summer in N hemisphere when it is winter in S hemisphere.
