Understanding Plate Boundaries

What are the three types of plate boundaries?

• Convergent, divergent, and transform

• Convergent, divergent, and parallel

• Parallel, perpendicular, and transform

• Convergent, perpendicular, and transform

What happens when two continental plates collide?

• Creation of new ocean floor

• Formation of rift valleys

• Subduction of one plate

What occurs at divergent boundaries?

• Plates collide and form mountains
