Why are the seasonal variations minimum in the equatorial regions?

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. http://en.wikipedia.org/wiki/Season The equatorial regions do not expierence the same degree of tilt (really no tilt) that either the southern or northern hemispheres do. Thus along the equator the seasons vary to a mininum. Jan 14 09, 1:29 AM
