Question

Quizplus · Accepted Answer

Seasons are caused by the Earth's orbital tilt relative to the plane of its orbit around the sun. This causes different parts of the planet to receive different amounts of sunlight at different times of the year, resulting in the four seasons. The distance between the Earth and the sun also plays a minor role, but it is not the main cause of the seasons.
