Plate Tectonics

Pangaea to today

Divergent Boundaries

Divergent boundaries move away from each other. They form sea-floor spreading and rift-valleys. An example is the island of Iceland.

Convergent Boundaries

Convergent Boundaries move into each other. If they don't have the same amount of density on plate will go over another and this is called convergent with subduction. They can form mountains and volcanoes. An example is the Appalachian Mountains in Eastern USA.

Here is what the Boundaries look like

Transforming Boundaries

Transforming Boundaries are boundaries that scrape across each other. They cause earthquakes and tsunamis and are on fault lines. An example is the San Andreas Fault in San Fransisico.
