What cause seasons

                                  What cause seasons

Seasons happen every year it starts from Autumn, Winter, spring, and finally summer.

In Autumn trees leaves falls off but before the leaves fall they turn into red, green, or yellow.

We have seasons because the earth is tilting on its axis. When the earth spins the sun shines on the northern hemisphere, it is summer and on the south hemisphere it is winter. So when the earth orbits the sun, it stays the same tilt, but the southern hemisphere is now pointing towards the sun. When when the sun shines on the southern hemisphere it is summer and the northern hemisphere is winter.
