Tectonic Plate Boundaries
Tectonic plates are the plates beneath us in the mantle that are constantly moving. There are 3 types of tectonic plate boundaries. Divergent, Convergent, and Transform. These plate movements are caused by convection currents in the Mantle.
The Theory Of Plate Tectonics
German Scientist, Alfred Wegner, came up with The Theory Of Continental Drift. This theory soon became the Theory Of Plate Tectonics. The word Tectonic came from the Greek word tektonikos, basically meaning "construction". The word tectonics is talking about the general structure of the Earth.
