Plate Tectonics IAN


Theory of plate tectonics

Crust and upper part of mantle broken into sections or plates


Lithosphere- plates



Gooey melted rock, top of mantle that the plates slide on




Plate boundaries

Edges of the plates, where they meet



Convection currents

Cause the plates to move

Heating, rising, cooling, sinking of magma-causes a current

Plate map- some plates large, some small
