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 lithosphereForms volcanoesMid-oceanic ridge formationEarthquakesCauses sea-floor spreadingThe America’s moving away from the Eurasian and African Plates formed the Mid- Atlantic RidgeFormed East –African Rift Valley

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 formMountain building (either folded or Island Arc)Deep –sea trench formationEarthquakesLAND IS DESTROYED!Andes Mountains-Nazca plate sinking underneath South American plate creating the Andes Mountains

Associated Landforms
Examples
Two plates
moving towards each other (continental crust toward continental crust)
Convergent
Collision
Results
in oogenesis (mountain) building.
Folded mountains formedNo volcanoes form here due to no magmaEarthquakes (deep and shallow)Himalayas-Indian plate moving into Eurasian plate forms the HimalayasSlide9

Associated Landforms
Examples
Two plates moving parallel
to each other/ moving sideways past each other.
Horizontal movement
Stick-slip process
Earthquakes

LAND IS NEITHER CREATED OR DESTROYEDSan Andres Fault-N American plate moving SEast and Pacific plate move Nwest.
