BY STARBOY...It is evidence that Mars had a molten core at one time and it is also evidence that the core is no longer molten. The molten core of the earth allows volcanic activity, a magnetic field and of course plate tectonics.

merlin writes...Yes, correct, but the magnetic field has nothing to do with gravity, as we understand it today. I suspect that the motions of the orbital perturbations of earth along with various other factors (which may include ringing!) instigate plate tectonic movements. Also these other events precipitate out gassing (volcanic activity) and many other geologic events.
