Imagine you are heating a bowl of custard on a gas hob (the custard is the magma), and then you leave it for a few seconds. The custard at the bottom warms up and the custard at the top cools down. If you stir it then all the custard has a turn at the bottom and the top of the pan. This is a mini convection current.
If you then put an object on this current then it will move in the same direction as the current. When you get two currents going in opposite directions then the two plates on top of the currents will collide causing an earthquake.
Just to point out I only just learnt this at school so don't blame me if I'm wrong!!!!

How do plates move where convection currents are risig?
The lithosphere is the continental crust, oceanic crust and upper part of the mantle. The convection currents move in the mantle mostly in the Asthenosphere layer under the lithosphere. As the convention currents move it makes the lithosphere spread and shake.
How does a convection current move rock?
How does a convection current move rock
How do Plates move where convection currents are rising-?
This tends to occur below a constructive / divergent plate boundary so the plates will move away from each other.
What is a Convection current model?
Convection currents in the mantle drag the plates like a conveyor belt.
Why do the plates of the lithosohere move?
Because of the convection currents in the mantel.
Do convection current in oceans cause tectonic plates to move?
No, convection currents in the upper mantle cause tectonic plates to move.
How do transform move?
convection current from the magma in the centre of the earth pushes plates to move.
Do you have to have heat in a convection current?
Yes, because otherwise, the plates, moved by the convection currents, won't move at all.
What is convection and how does it cause plates to move?
What is convection and how does it cause plates to move? What are the consequences of convection in the mantle?

What is the convection current hypothesis?
The convection current hypothesis supposes that convection currents in the Earth's Mantel (the zone below the surface/crust and above the Earth's core) cause the movement of the tectonic plates (plates that make up the surface/crust of the Earth and shift/move on a grand time scale).
How do Plates move where convection currents are rising-?
This tends to occur below a constructive / divergent plate boundary so the plates will move away from each other.
Do convection currents in the oceans cause tectonic plates to move?
No, convection currents in the upper mantle cause tectonic plates to move.
What causes your plates to move?
convection currents!
What do lithospheric plate movements have to do with convection?
there is convection in the mantle. it causes the plates to move.
What drives the plates together and apart?
Convection Current
