Natural Science Forum / Physics / Relativity / August 2005Earth Core Rotating Faster
If as they say the Earth's core is rotating faster than the outer portions wouldn't it transmit causing the day to get shorter? > If as they say the Earth's core is rotating faster than > the outer portions wouldn't it transmit causing the day > to get shorter? Actually, just the opposite is true. The day is really getting longer due to the effects of tidal friction slowing the rotation down. But don't expect to notice it very much.

Nick is probably referring to this: http://www.sciencedaily.com/releases/2005/08/050826081334.htm Klazmon. > "Igor" <thoovler@excite.com> wrote in news:1125452861.406599.252400 > @g47g2000cwa.googlegroups.com: [quoted text clipped - 12 lines] > > Klazmon. Interesting, but at only 0.3 to 0.5 degrees per year, it's a very small, but yet significant, difference. Besides, it says the outer core seems to act as a buffer, decoupling its motion from the mantle. But it's interesting nevertheless. |
