Plate Margins

Destructive Margin:

The oceanic plate and continental plate move towards each other due to convection currents. They met and the MORE dense OCEANIC plate is forced underneath. Friction buids up and can cause earthquakes. The oceanic plate melts in the subduction zone building up pressure until it is released as a volcano.

Example - Nazca and South American plates

Constructive Margin:

Two plates (oceanic…
