PRESENTATION OUTLINE
PLATE TECTONICS
PIECES OF THE LITHOSPHERE ARE IN SLOW CONSTANT MOTION
CONVECTION CURRENTS
THE FLOW THAT TRANSFERS HEAT THROUGH FLUIDS
SLAB PULL
THE PULL OF GRAVITY ON A PLATE THAT IS BEING SUBDUCTED
Ridge Push- NEW CRUST FORMING AT DIVERGENT PLATE BOUNDARY PUSHES OLDER CRUST OUT OF THE WAY OLDER, DENSER CRUST GETS PULLED AWAY BY GRAVITY
DIVERGENT
PLATES MOVE AWAY FROM EACH OTHER
RIFT VALLEY
LAND FORM THAT RESULTS FROM DIVERGENT PLATE BOUNDARY
MID-OCEAN RIDGE
UNDER WATER LANDFORM THAT IS CAUSED BY A DIVERGENT PLATE BOUNDARY
CONVERGENT PLATE BOUNDARY
WHEN TWO TECTONIC PLATES COME TOGETHER
VOLCANIC ARC
WHEN AN OCEANIC PLATES AND CONTINENTAL PLATES
ISLAND ARC
FORMS WHEN TWO OCEANIC PLATES CONVERGE
CONTINENT VS CONTINENT
A FAULT IS CREATED
SUBDUCTION Zone
ONE PLATE GOES UNDER THE OTHER ONE WHEN THEY COLIDE
DEEP OCEAN TRENCH
DEEP VALLEY ON THE OCEAN FLOOR UNDER WHICH OCEANIC CRUST SINKS TOWARD THE MANTLE
