THE CONTINENTS MOVE BECAUSE THE MANTLE IS MOVING BELOW THEM

GRAVITY IS PULLING THE PLATES IN THE SUBDUCTION ZONE

SEAFLOOR SPREADING PUSHES THE PLATES APART

OCEANIC CRUST IS FORMED THROUGH UNDERGROUND VOLCANIC ACTIVITY.

IT CAN MAKE A CANYON OR A VALLEY

CAN RESULT IN A RIVER OR A SUBDUCTION ZONE

WHEN TWO PLATES MOVE TOWARD EACH OTHER AND COLLIDE

OCEAN VS CONINENT

CONTINENT VS CONTINENT

WHEN ONE TECTONIC PLATE MOVES UNDER ANOTHER TECTONIC PLATE

A TRENCH DEEP IN THE OCEAN

IT NEITHER CREATES OR DESTROYS PLATES

THEY SLIDE PAST EACH OTHER AND CONTINUE MOVING
