You will find that the coefficient of friction is in large part caused by the pressure created when gravitational forces cause the plates to bear down on the lower divisions of the lithosphere.sandy_mcd wrote: Please explain the derivation of this formula - no traditional geologist says the continents are moving because they are acted upon by gravity which is what this formula asserts.
The force of gravity is one of the variables involved in countering the unknown force that caused pangea to break apart. I have seen the mass of the water in the global flood, and an asteroid hypothesized.
Gravity is the force involved in the resistance to movement by any mechanism of continental drift.
Also Sandy_mcd I think you may be slightly confused by that formula because you see the word acceleration, and are assuming that formula is measuring that force of causing the continents to move.
This is not the case it is measuring the acceleration (which actually simply denotes a change in speed in this case a reduction) involved in the rate the speed of the continents change from the frictional forces while they are coming to rest.
