Reasons for the Seasons!
The Earth has day and night according to the fact that we turn on our axis. This makes one side of Earth face the Sun while the other is in darkness. It takes 24 hours for 1 rotation. It takes 365.25 days for 1 full revolution. We get seasons from the tilt of the earth and the direct or undirect sunlight. In the Southern Hemisphere it is totally the opposite season in the northern Hemisphere. Near the equator doesn't experience season change because they are getting same amount of sunlight year round. In the summer the days are the longest and in the winter they are the shortest.This is only true in the Northern Hemisphere, though.The summer solstice is on December 21, and the winter solstice is on June 21. Spring and fall are equal days and nights, spring starts march 21, fall starts September 21.At the south pole the sun rises, and at the north pole it sets for six months.At the equinox the Earth's axis is not tilted toward the sun and the day is about 12 hours long over most of the Earth,near the Equator there is little difference between summer, winter, fall, or spring that are the length of days in the equator. I think the Earth would have no seasons because without the tilt there are no seasons.
