What causes the seasons? The seasons are caused by the tilt of the Earth's rotational axis away or toward the sun as it travels through its year-long path around the sun. The Earth has a tilt of 23.5 degrees relative to the ecliptic plane (the imaginary surface formed by it's almost-cicular path around the sun).
It's a Matter of Tilt. The biggest reason for the seasons is that Earth's axis is tilted relative to its orbital plane. It may be that way because of a large impact in our planet's history that could be responsible for the creation of our Moon. The infant Earth was smacked pretty heavily by a Mars-sized impactor.
