Plate Boundary • Place where edges of tectonic plates meet.
• 3 Different types of plate boundaries based on motion of the plates:
Convergent Boundary
• When two plate collide or crash into each other.
• 3 Possibilities:– Oceanic into Oceanic
– Oceanic into Continental
– Continental into Continental
•
Convergent Boundary
• One plate must go under the other. This is called Subduction.
• Subduction only occurs at convergent boundaries
Divergent Boundary
• When two plates move away from each other
• Sea floor spreading
• New lithosphere is created to fill the “gap.”
