LITHOSPHERE ARE IN SLOW CONSTANT MOTION DUE TO CONVECTION CURRENTS IN THE MANTLE

THE TRANSFER OF HEAT SEPARATING BY DENSITY WHEN MIXED WITH COOLER FLUID

PULL OF GRAVITY ON A PLATE THAT IS BEING SUBDUCTED

NEW CRUST FORMING AT DIVERGENT BOUNDARIES PUSHES OLDER CRUST OUT OF THE WAY AND OLDER DENSER CRUST IS PULLED BY GRAVITY

CONTRIBUTES TO SEA FLOOR SPREADING SPLITS THE OCEANIC CRUST AS PLAYES MOVE AWAY FROM EACH OTHER

LAND FORM THAT RESULTS FROM A DIVERGENT PLATE BOUNDARY

UNDERWATER MOUNTAIN RANGE FORMED BY DIVERGENT PLATE BOUNDARY

TWO OR MORE FRAGMENTS OF THE LITHOSPHERE MOVE TOWARD EACH OTHER AND COLLIDE

THIS FORMS WHEN AN OCEANIC PLATE COLLIDES WITH A CONTINENTAL PLATE

FORMED WHEN TWO OCEANIC PLATES COLLIDE

SYSTEM OF MOUNTAINS USED TO COMBINE TWO CONTINENTAL PLATES BY CONVERGENT BOUNDARIES

A COLLISION WHERE ONE PLATE SLIPS BENEATH THE OTHER BY CONVERGENT BOUNDARIES

A DEEP DEPRESSION IN THE OCEAN FLOOR DUE TO SUBDUCTION ZONES

A DEEP OCEAN TRENCH OVER 5 MILES DEEP

WHEN TWO TECTONIC PLATES SLIDE PAST ONE AND OTHER

A SUDDEN RELEASE OF ENERGY IN EARTHS CRUST CREATING SEISMIC WAVES

TRANSFORM BOUNDARY FAULT THAT EXTENDS ROUGHLY 810 MILES
