CONVECTION CURRENTS

THE FLOW THAT TRANSFERS HEAT THROUGH A FLUID

SLAB PULL

THE PULL OF GRAVITY ON A PLATE THAT OS BEING SUBDUCTED

RIDGE PUSH

HAPPENS AT SPREADING CENTERS WHERE PLATES ARE MOVING APART

DIVERGENT PLATE BOUNDARY

TWO PLATES ARE MOVING AWAY FROM EACH OTHER

RIFT VALLEY

LANDFORM THAT RESULTS FROM A DIVERGENT PLATE BOUNDARY

MID OCEAN RIDGE

UNDERWATER LANDFORM THAT IS CAUSED BY A DIVERGENT PLATE BOUNDARY

CONVERGENT PLATE BOUNDARY

THE PLACE WHERE TWO PLATES COME TOGETHER OR CONVERGE

VOLCANIC ARC WITH TRENCH

LANDFORM RESULTING FROM OCEANIC VS. CONTINENTAL PLATE BOUNDARY

TRENCH WITH ISLAND ARC

LANDFORM RESULTING FROM OCEANIC VS. OCEANIC PLATE BOUNDARY

MOUNTAIN RANGE

LANDFORM RESULTING FROM CONTINENT VS CONTINENT PLATE BOUNDARY

SUBDUCTION ZONE

THE ACTION IF PLATE TECTONICS OF THE EDGE OF CRUST PLATE SLIDING BELOW THE OTHER

DEEP OCEAN TRENCH

STEEP SIDED DEPRESSION IN EARTH'S CRUST USALLY LYING ABOVE A SUBDUCTION ZONE

MARIANA TRENCH

IT'S AN EXAMPLE A DEEP OCEAN TRENCH

TRANSFORM PLATE BOUNDARY

A FAULT THAT OFFSETS A MID OCEAN RIDGE IN OPPOSITE DIRECTIONS OF SEA FLOOR SPREDING

FAULT

LAND FORM RESULTING FROM TRANSFORM PLATE BOUNDARY

SAN ANDRES FAULT

THE SAN ANDRES FAULT IS AN EXAMPLE OF A TRANSFORM PLATE BOUNDARY
