Quizplus · Accepted Answer

The seasons are actually caused by the tilt of the Earth's axis. As the Earth orbits the sun, different parts of the globe receive different amounts of sunlight at different times of the year, resulting in the four seasons. The precession of the Earth's axis does have an effect on the timing of the seasons over long periods of time (around 26,000 years for a complete cycle), but it is not the primary cause of the seasons.
