Boundary where new crust is formed.
Divergent
Upper mantle and crust are broken into pieces called ______ plates?
Tectonics
———–

Individual that proposed the continental drift theory.
Alfred Wagner
—————-
Large land mass or supercontinent meaning “all land”
Pangea
Boundary where plates move apart
Divergent
Uppermost layer of mantle that is made up of tectonics plates
Lithosphere
Boundary where plates collide
Convergent
Boundary where plates slide past each other
Transform
Area/zone where one platessinks below the other
Subduction
The main driving force in the plates moving is this
