Slide1

Plate Boundaries Slide2
Slide3

Construcive (Divergent)Slide4

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 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

Destructive (Convergent)Slide6

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

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 formedNo volcanoes form here due to no magmaEarthquakes (deep and shallow)Himalayas-Indian plate moving into Eurasian plate forms the HimalayasSlide9

Conservative Plate Margins (Transform)Slide10

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)

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