Plates move for more than one reason.
1) Ridge-push forces: the sea floor is sloped and the high elevations on ocean ridges create a force that pushes the plate away.
2) Slab-pull force: Plates that subduct pull the plate down
3) Convection in the Mantle. The lithospheric part of the mantle cannot convect and sits on top of the asthenospheric part of the mantle that can convect. The convection causes flow through the asthenosphere, which causes the lithospheric plates on top to slowly move.

∙ 12y agoDr. Alfred Wegener proposed the continental drift theory which states that the lithosphere drifts apart because of the gravitational pull of the moon. Harold Jeffreys contradicted the idea. He said that if Dr. Wegener's proposal is true, then the gravitational pull of the moon could stop the Earth from moving. The Earth is still moving today. There is another theory called Seafloor Spreading which states that the oceanic crust moves apart forming cracks. The magma goes through these cracks and up until it cools. When it cools it sinks and goes through the cracks. This is why our seafloor is very young. The sea floor is recycled. The most acceptable theory is the Plate Tectonics theory which is the combination of Continental Drift Theory and Sea floor Spreading.
I hope this helped you a lot. This is a stranger helping a stranger. I hope this will strengthen our mutual relationship. Thank you!

∙ 8y agoThe continental tectonic plates are areas of the crust that we live on. Beneath the crust is the mantle - which is a semi-fluid layer of molten rock. Being molten, the mantle layer is always on the move - which means that the crust laying on top is also floating.

Large crustal plates moving on the earth's surface are?
Tectonic plates.
What does moving of techtonic plates cause?
the moving of techtonic plates causes mountains and underneath the ocean they make trenches ect.
Are the pacific plates and the antarctic plates moving towards each other or away from each other or past each other?
the plates are moving away from each other.
What evidence reasoning to geologist use to support the idea that plates are moving?
It is no longer an idea for some time that plates are moving. It is a fact. Earthquakes and todays technology prove the fact that the earths plates are moving. Tsunamis are caused by earthquakes.
What is a possible result of plates moving along a transform boundary?
a possible result of plates moving past each other is an earth quake
Do the continental plates remain in one place?
No, both the continental and oceanic plates are always moving. Moving slowly, but always moving.
How do you use the word tectonic plates in a sentence?
Example sentence - The tectonic plates are always moving.
Are tectonic plates always moving?
yes, just very slowly
Why are the plates of the crust always moving?
Because the mantle has convection currents that push the plates around very slowly.
How do you use the word plate in a sentence?
Example sentence - The tectonic plates are always moving.
When do destructive plates move?
They are always moving little by little. It is a very interesting topic.
When was Moving Gelatine Plates created?
Moving Gelatine Plates was created in 1968.
What is another word for tectonic plates?
moving plates
What causes plates to stop moving temporarily?
Friction causes plates to stop moving temporarily. The motion of the magma under the plates will cause the plates to move again.
What happens if earthquake is under land?
its always underground, the shock waves from the moving plates go up through the crust
What are two plates moving away known as?
Divergent plates
What are moving pieces under the earths surface that form the earths crust?
The answer is tectonic plates floating on the lithosphere. Does that answer your question? LOL :)
