In the middle of a plate
Nothing, all parts of the earth are moving relative to the other parts.
The epicenter is located (above the focus) at the earth's surface.
The theory of Plate Tectonics
Moving Gelatine Plates was created in 1968.
moving plates
Friction causes plates to stop moving temporarily. The motion of the magma under the plates will cause the plates to move again.
No, both the continental and oceanic plates are always moving. Moving slowly, but always moving.
The majority of earthquake zones are located at tectonic pate boundaries because it is the relative motion of the plates that causes earthquakes.
Divergent plates
The answer is tectonic plates floating on the lithosphere. Does that answer your question? LOL :)
If the plates are moving together from opposite directions, the colliding edges will uplift into mountain ranges. If the plates are moving apart, a rift valley will form. If the plates are moving together at oblique angles, a fault zone will occur.
But plate tectonics is the theory which suggests that the Earth's crust is made up of solid plates moving relative to each other. Plate tectonics and the plate tectonics theory aren't really two separate things. However plates are pieces of the Earth's crust which are moving.
