Who Is Alfred Wegener?
Alfred Wegener Is the scientist that theorized plate tectonics, plate tectonics is a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates that move slowly over the underlying mantle.

Definitions:
1) Convergent boundary- is an actively deforming region where two or more tectonic plates of the lithosphere move toward each other and collide.
2) Divergent boundary-a linear feature that exists between two tectonic plates that are moving away from each other.
3) transform boundary- occurs when two plate tectonics slide alongslide eachother.
