3. Sci 10 – Class Starter

4. Sci 10 – Class Starter
What are the three forces that provide the mechanism for plate movement?
Mantle convection: Plates pushed in a similar way to a conveyer belt
Ridge Push: As new magma cools it increases in density and pushes the plates to each side
Slab pull: As plates are subducted convection currents and gravity pull the plate down
What type of boundary (divergent, convergent or transform) and what types of plate interaction (oceanic and continental) leads to land mountain formation?
Convergent + Continental-Continental Plate Boundary
What type of boundaries do rifts form?
Divergent plate boundaries (continental-continental)
What type of boundaries do trenches form?
Convergent plate boundaries (oceanic-continental or oceanic-oceanic)
