Yes they do.
Tectonic plates are made of the Earth's crust. The convection caused by the mantle makes them move.
Constructive because new land is 'constructed'
The sea mounts help us understand the movement of tetonic plates because when the tetonic plates move's the earth's crust making little formations of sand underwater.
Plates move apart on divergent plate boundaries.
Well, when earths plates move away from each other that's when it happens but move well then NO!
yes
You make a model of a ground and then you use a metal peice and model it into a tetonic plate and try to make it move.
In human history no state has had to move because of the Earth's plates.
When the plates move apart they will more than likley create a large creak, Depending on how far they move apart. It would be a small creek.
Continental Plates
most people in calafornia are really fat and they move about wobbleing the tetonic plates.
