One suggestion for the cause of plate tectonics is mantle convection which is the result of cooling and heating magma. You could think of mantle convection much in the same way lava flows in a lava lamp. Lava rises in a lava lamp because it heats up and becomes less dense. While at the top of the lava lamp, the heated lava begins to cool (because it's further away from the heat source (e.g. light) at the bottom) becoming more dense and then sinks back down to the original heat source where it will be reheated.
This mantle convection is thought to work somewhat like a large conveyor belt in which the plates sit, moving them along.
No, convection currents in the upper mantle cause tectonic plates to move.
Because tectonic plates move, therefore if the continent is on it, it moves with it!
no
Spredading of tectonic plates causes Tsunamis, Earthquakes, Volcanic erruptions, etc.
there are 7 huge plates but dozens of smaller plates
Yes!
The movement of tectonic plates.
Tectonic plates that slipped.
Shifting of tectonic plates.
Tectonic plates
tectonic movement can cause tectonic plates to collide, drift apart, or slide across one another
When the tectonic plates cause earthquake, it creates a crater in earth. This opening can lead to a volcano.
