Answer:As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons.
In other words: Earth has seasons because its axis is tilted. Earth's axis is always pointed in the same direction, so different parts of Earth get the Sun's direct rays throughout the year. ... Many people believe that Earth is closest to the Sun in summer and farthest in winter...
If you don't understand those ways here's one you may understand: The reason we have seasons is because, during its journey around the Sun, the Earth is tilted. The Earth's tilt affects the amount of daylight each hemisphere gets, which in turn makes the temperature hotter or colder.
Those are some ways we have seasons...
By the way, what's your favorite season???
Hope this helps.. Stay safe and have a great day/night!!! :D
