Why isn't Earth torn apart by time?

Kenneth Silva  asked the Naked Scientists:
There's an experiment using 2 atomic clocks, one on Earth and the other in space. Since one is moving faster than the other, they travel through time at different rates (according to Einstein).
It occurs to me that even the top of a tall mountain is therefore moving faster than a deep valley, so they are experiencing the passage of time at different rates.

So, why isn't planet Earth torn apart, since different parts are moving through space-time at varying rates of speed? Or, am I just loony?

This was discussed a month ago in Is the equator older than the poles?. The answer is that the poles have aged more than the equator, but the difference is less than one day in a billion years. That results in a very tiny amount of stress. It's not even a significant part of the stress that drives plate tectonics.
