PLATE TECTONICS
BY JAMES RASTATTER
PLATE TECTONICS
THE LITHOSPHERE IS BROKEN INTO PIECES THAT MOVE
CONVECTION CURRENTS
MOVEMENT IN MANTLE DUE TO DIFFERENCE IN DENSITY
SLAB PULL
GRAVITY PULLING ON A SUBDUCTION PLATE
RIDGE PUSH
MAGMA PUSHING THE EGDES OF DIVERGING PLATES APART
DIVERGENT PLATE BOUNDARY
PLATES MOVE AWAY FROM EACH OTHER
RIFT VALLEY
EAST AFRICAS GREAT RIFT VALLEY THAT RESULTS FROM A DIVERGENT PLATE BOUNDARY
MID OCEAN RIDGE
THE MID ATLANTIC RIDGE THAT IS CAUSED BY A DIVERGENT PLATE BOUNDARY
CONVERGENT PLATE BOUNDARY
WHEN BOTH OF THE TECTONIC PLATES IS COMPOSED OF OCEANIC CRUST WERE PLATES COLLIDE
MOUNTAIN RANGE
ST.HELENS IS A FORM OF CONVERGENT PLATE BOUNDARY
TRENCH WITH VOLCANIC ARC
THE RING OF FIRE IS A RESULT OF CONSTRUCTIVE PLATE BOUNDARY
TRENCH WITH ISLAND ARC
THE MIRANDA TRENCH IS AN EXAMPLE OF CONVERGENT PLATE BOUNDARY
SUBDUCTION ZONE
THE PROCESS WERE THE PLATE SINKS INTO THE MANTLE
DEEP OCEAN TRENCH
A TRENCH THAT IS UNDERWATER
DEEP OCEAN TRENCH
MID OCEAN RIDGE IS A RESULT OF DEEP OCEAN TRENCH
RESULTING IN A TRANSFORM PLATE BOUNDARY
A FAULT
TRANSFORM PLATE BOUNDARY
2 PLATES THAT SLIDE PAST EACH OTHER
