What Causes the Seasons to Change?
What causes the seasons to change? The first answer many people give when asked why the Earth gets cold in the winter and warm in the summer is because the Earth’s distance from the sun can vary during its orbit. Astronomers have carefully measured the distance between the Earth and Sun and have discovered that the Earth is closest to the Sun in January, and farthest away in July.
But wait a second! January is the peak of winter in the Northern hemisphere, and July is the peak of summer. There is another problem with the distance/season misconception: Why is it that when it is summer in the Northern hemisphere, it is winter in the Southern hemisphere? Something else besides varying distances from the sun must be causing the seasons.
