Document Summary
Passive plate margins differ greatly from active margins because of their proximity to plate boundaries. Passive margins are located within the interior of the lithosphere and are not close to any plate boundaries. This causes a passive margin to be void of major tectonic activity such as volcanoes, earthquakes, and orogeny. One example would be the united states east coast. Active margins are centers of high tectonic activity because of their proximity to lithospheric plate boundaries. There are two types of active margins; convergent and transform. In a convergent active margin, oceanic and continental plates are colliding such as in south america where the nazca plate is being subducted under the south american plate. An example of a transform active margin exists in coastal california where the san andreas fault is a transform plate boundary. A passive continental margin includes many telling features.
