On Dec 15, 1995 ZetaTalk stated that the Rotation of the Earth and other planets with a liquid core was driven by the core. On July 18, 1996 the Lamont-Doherty Earth Observatory findings were published in News Articles showing that the core of the Earth turns faster than the crust, thus driving the process.
Core Spins Faster Than Earth, Lamont Scientists Find
Columbia University, Lamont-Doherty Earth Observatory
The inner core rotates in the same direction as the Earth and slightly faster, completing its once-a-day rotation about two-thirds of a second faster than the entire Earth. Over the past 100 years that extra speed has gained the core a quarter-turn on the planet as a whole, the scientists found. Such motion is remarkably fast for geological movements -- some 100,000 times faster than the drift of continents, they noted. The scientists made their finding by measuring changes in the speed of earthquake-generated seismic waves that pass through the inner core.
