Mid-ocean ridge The undersea mountains chain where new ocean floor is produced
Convergent boundary The place where 2 plates have come together
Divergent boundary The place where 2 plates move apart
Transform boundary The place where 2 plated have slipped past one another
Lithosphere A rigid layer made of the uppermost part of the mantle and crust
Asthenosphere The soft layer of the mantle on which the lithosphere floats
