Plate Tectonics Information

Plate Boundaries:

 Convergent; Oceanic Vs. Oceanic: a plate tha is more dense sinks into a trech.

Convergent; Continetal Vs.Continetal: SInce they ar eboth equal, they ush against each other forming a mountain (himalayas)

Convergent; Oceanic Vs. Continetal: More dense oceanic crust sinks under the continetal pushing it up. (indies)

Divergent; Oceanic: Splits the land underwater making a mid-ocea ridge.

Divegent; Continetal: Splits the land up and turns the divergent boundary into a convergent boundary.

Transform: Plates that slide past each other in opposite diretions.

Crust Types:

Continetal: On land, younger, less dense, thicker

Oceanic: Underwater, older, more dense, thinner

Landforms Created by Plate Tectonics:

Deep Ocean Trench: A proceess taking tens of millons of years where part of the ocean floor sinks bak into the mantle (bends downward)

Mid Ocean Ridge: Forms long chains of mountians that rise up from the ocean floor.
