Since earliest times, man has been curious about the changing of the seasons. There are a lot of questions. Why is it warm in summer and cold in winter? Why do the days gradually grow longer in the spring? Why are the nights so long in winter?
In ancient times people thought that Gods were changing the weather and the seasons.
As we know now the earth revolves around the sun, and at the same time it revolves on its own axis. The axis of the earth isn’t at right angles to the path of the earth around the sun. The reason for this is a combination of forces: the pull of the sun, the pull of the moon, and the spinning action of the earth itself. The earth goes around the sun in a tilted position. It keeps that same position all year, so that the earth’s axis always points in the same direction, toward the North Star.
