PIECES OF EARTHS LITHOSPHERE ARE IN SLOW CONSISTANT MOTION WHEN CONVECTION CURRENTS IN THE MANTLE.

THE MAIN SOURCEIS CONVECTION CURRENTS IN THE MANTLE (MANTLE CONVECTION)

GRAVITY PULLING ON THE PLATES IN THE SUBDUCTION ZONES (SLAB PULL)

NEW CRUST FORMING PUSHES THE TECTONIC PLATES APART (RIDGE PUSH)

A BOUNDARY WHERE PLATES ARE MOVING APART.

MID-OCEAN RANGE, FORM A RIFT VALLEY WHEN THEY OCCUR ON LAND.

MID-OCEAN RANGE IS AN EXAMPLE.

A PLACE WHERE TWO PLATES CONVERGE (COLLIDE)

DENSITY DETERMINES THE OUTCOME OF PLATE COLLISION.

WHEN OCEAN CRUST COLLIDES WITH CONTINENTAL CRUST, A DEEP OCEAN TRENCH FORMS.

WHEN TWO CONTINENTAL PLATES COLLIDE, MOUNTAINS FORM.

IS THE PROCESS BY WHICH OCEAN CRUST SINKS BENEATH A DEEP OCEAN TRENCH AND BACK INTO THE MANTLE.

IS FORMED AT AN OCEANIC RIDGE WHILE THE LITHOSPHERE IS SUBDUCTED BACK INTO TRENCHES.

SUBDUCTION ZONES OFF OF WEST COAST OF SOUTH AFRICA. ALEUTIAN TRENCH DEEPEST AND MOST FAMOUS.

A PLACE WHERE TWO PLATES SLIP PAST EACH OTHER MOVING IN OPPOSITE DIRECTIONS.

AS 2 PLATES SLIDE PAST ONE ANOTHER IN TRANSFORM BOUNDARY NIETHER IS ADDED OR DESTROYED.

EARTHQUAKES OCCUR FROM A TRANSFORM BOUNDARY BECAUSE IF THE PLATES SLIDING PAST ONE ANOTHER.
