Three ideas of why we have seasons

1.  The rotation of earth- The rotation of earth also can determine which part of the

hemisphere is getting more light.

2.  The axis-  The point of the axis determines winter and summer and spring, and

autumn in between.  If the axis is pointing upwards that hemisphere is receiving more

light (summer) as for the axis farther back is receiving less light (winter).

3. Orbit of the sun-  It takes the sun 365 days (1 year) for a full rotation.  As each

part of the earth moves closer to the sun, that bit of land will recieve heat and light.
