Seasons
Why we have seasons: Earths tilt is the cause of seasons, when the earth is tilting toward the sun the northern hemisphere is getting more direct sunlight making it summer and the southern hemisphere is getting less direct sun making it winter. the opposite when tilting away north winter less sun, south summer more sun. and when the tilt is neither then both north and south are fall or spring depending on whether they were summer or winter before.
