<< Movements in the tectonic plates cause slight variations, >> Did you know that because we have a tendency to dam up rivers, there has been a net movement of water away from the equator and toward the poles (specifically, mostly this happens in the northern hemisphere), so human activity is speeding up the rotation of the Earth. (Technically, the moon's tidal drag is slowing it down even more, but we're reducing the moon's slowing-down effect. :-P ). Stephan "Ain't it cool?"
