Earth’s seasons are caused by the combination of its orbit around the Sun and the tilt of Earth’s axis in relation to that orbit. These factors cause the height of the Sun’s path, as seen from any given location, to change throughout the year. The height of the Sun in the sky determines how much heating will take place.
