12.4 What is the evidence that subduction occurs at convergent plate boundaries?

• Convergent boundaries contrast with divergent ones in three main ways:
• Plates move toward one another rather than apart.
• Subduction destroys lithosphere at convergent boundaries rather than creating it.
• Convergent boundaries are highly asymmetrical, with one plate angled downward beneath its neighbor, whereas divergent boundaries are vertical, symmetrical boundaries.
