Mechanism of Plate Movement Flashcards
either tectonic plates toward one another or pull them apart
driving forces
circulation of materials by different density
mantle convection
when subducting slab sinks into the hot mantle because of different temperatures
slab pull
occurs when two colliding plates, one is subducting underneath the other
slab suction
created force that pulls down plates as they are subducting
slab suction
lithosphere is pushed up by the asthenosphere
ridge push
act against driving forces of plate tectonics
resisting forces
resists all forces associated with the plate movement in subduction zone
slab resistance
occurs when HEAVY PLATE is pulled into the mantle but resists subduction because of friction
collisional resistance
frictional force due to the opposing movements of plates
transform fault resistance
resists movements of lithospheric plates
drag force
