The
seasons result from the Earth's axis being tilted to its orbital plane; it deviates by an angle of approximately 23.5 degrees. Thus, at any given time
during summer or winter, one part of the planet is more directly exposed to the
rays of the Sun (see Fig.
1). This exposure alternates as the Earth revolves in its orbit. Therefore,
at any given time, regardless of season, the northern and southern
hemispheres experience opposite
seasons.
The
effect of axis tilt is observable from the change in day length, and altitude of the Sun at noon (the culmination of the Sun), during a year… so-
STOP !
STOP , STOP , STOP !
Oh,
sorry (for going off-topic …)…
