Earth's rotation and tectonic plates?
Without any mountains on earth, would the important speed of Earth's rotation make tectonic plates constantly shake and slide ?
my question is about the effect of Earth's rotation on tectonic plates, not the effect of mountains on Earth's rotation.

The speed of this rotation is constantt, thus Earth's rotation doesn't make the tectonic plates move faster or shake.
Mountains don't change anything. However, I remember that a theory supports that rotation of earth may create faults on crust.
Mountains don't protect the plates from colliding: these mountains ARE formed by "plate collisions".
They don't protect plates movement either.
For example: the collision of the Indian and Euroasian plates, which created the Hymalaya, keep on moving.
Even the borders of plates, thus the mountains, move!
The assertion "the mountains stabilize earth" isn't confirmed by the geologists.
In fact, Noushad Bin Jamal's claim is devoid of scientific evidences.
I hope it'll answer to your question, silveren...

No. Mountains have no affect on the rotation of the earth or the movement of tectonic plates. If they had an affect on plate movement, then there would be some sort of different evidence in areas there are no mountains vs. areas with mountains.
Relative to the diameter of the earth the angular momentum of the mass on top of a mountain is insignificant to affect the rotation of the earth.

All the rocky planets have (or have had) tectonic features. As an aside, plate tectonics was laughed at by professional geologists up until about 50 years ago. The first proposal for plate tectonic motion was made about a hundred years ago, and the poor guy who was suggesting this theory was laughed out of conferences and stuff like that. My, how things change. In the 1950s, surveys of the ocean bottoms revealed the mid Atlantic ridge structure and close examination revealed the spreading of the ocean floor... and now it's hard to imagine that scientists ever didn't believe in it! In the referenced Wikipedia article, the "not generally accepted" comment in the "development of the theory" section is the polite way to say what I said less "politically correctly" above.

well .. your question is about the effect of earth's rotation on tectonic plates?..
As you know that earth has crust, mantle and core,
the plate tectonic theory states that plates are moved apart from each other over a fluid called magma,
you kknow that the gravity is influenced on a body by the strong magnetic field created by the electric field by continous boiling of Nickel and Iron inside the core as the rotation of celestial bodies are relative to their mutual attraction, caused by their own gravitational force, you might have noticed the tidal effects.
now you should know that the mountains as you see above the surface of earth, they are deep in to the earth three times than their height, and they protects plates movements.. this is not said by me , its a scientific fact...
relating to the above , we can say that mountains are protecting the plates from collision of each other, and plates may move over magma, and the movement can be accelerated if there is no mountain....

No. The rotation of the Earth doesn't have much effect on plate movement. The plates are driven by hot magma welling up from the hot core of the Earth.

No... guess where i got that answer..... ya even if the earth wasnt spinning the plates would still move, that is if the earth behaved exactly as it does now. rock melts, becomes magma, forces other magma to the surface causing movement and when the plates collide!!!!! then mountains form. heres my diagram.
1.) _______ -> <- _____________
2.) _____________ -> <-______________
vhala. the displaced earth either moves up on both sides causing a large mountain, one moves on top of the other plate causing hills, small mountains, etc. and that earth is then melted causing more movement, or shifts in the plates. Its as simple as that
Wikipedia probably couldve explained it moreSource(s): im a teenager, i know everything
