Plate Boundaries Construcive (Divergent) Plate Movements Geological Process Associated Landforms Example • Two plates of the oceanic crust moving apart from each other • Two plates of continental crust moving apart from each other • Upwelling of magma • Creation of new lithosphere • Forms volcanoes • Mid-oceanic ridge formation • Earthquakes • Causes sea-floor spreading • The America’s moving away from the Eurasian and African Plates formed the Mid- Atlantic Ridge • Formed East –African Rift Valley http://teachertu be.com/viewVid eo.php?video_id =147431 Destructive (Convergent) Plate Movements Geological Processes Associated Landforms Examples • Two Plates moving towards each other (oceanic crust towards continental crust) converging results in the seduction of oceanic plate • Convergent • Seduction-creates oceanic trench • Creation and upwelling of magma. • Volcanoes form • Mountain building (either folded or Island Arc) • Deep –sea trench formation • Earthquakes LAND IS DESTROYED! Andes MountainsNazca plate sinking underneath South American plate creating the Andes Mountains http://teachertube.com/view Video.php?video_id=78053&t itle=Convergent_Boundary Collision Plate Margins Plate Movements Geological Processes Associated Landforms Examples • Two plates moving towards each other (continental crust toward continental crust) • Convergent • Collision • Results in oogenesis (mountain) building. • Folded mountains formed • No volcanoes form here due to no magma • Earthquakes (deep and shallow) HimalayasIndian plate moving into Eurasian plate forms the Himalayas Conservative Plate Margins (Transform) Plate Movements Geological Processes Associated Landforms Examples • Two plates moving parallel to each other/ moving sideways past each other. • Horizontal movement • Stick-slip process • Earthquakes (shallow) San Andres Fault -N American plate moving SEast and Pacific plate LAND IS NEITHER CREATED move Nwest.
