Earth’s changing position with regard to the Sun and the moon has noticeable effects.
Earth revolves around the Sun with its rotational axis tilted at 23.5 degrees to a line perpendicular to the plane of its orbit, with the North Pole aligned with Polaris.
During Earth’s one-year period of revolution, the tilt of its axis results in changes in the angle of incidence of the sun’s rays at a given latitude; these changes can cause variation in the heating of the surface. This produces seasonal variation in weather.
