THE LITHOSPHERE IS BROKEN INTO PIECES THAT MOVE IN A SLOW CONSTANT MOTION

CONVECTION CURRENTS

FLOW THAT TRANSFERS HEAT WITHIN A FLUID. HOT, MORE DENSE, RISES. COLD, LESS DENSE, SINKS

SLAB PULL

GRAVITY PULLS ON THE ENDS OF PLATES AT SUBSUCTION ZONES AND PULLS THEM TOWARD THE CENTER OF EARTH.

RIDGE PUSH

NEW, LESS DENSE CRUST FORMS AT DIVERGENT BOUNDARIES BY PUSHING OLDER, DENSER CRUST OUT OF THE WAY

DIVERGENT PLATE BOUNDARIES

BOUNDARY WHERE PLATES ARE MOVING APART FROM EACH OTHER

ÁLFAGJÁ RIFT VALLEY IN SOUTHWEST ICELAND

LANDFORM RESULTING FROM THE DIVERGENT BOUNDARY BETWEEN THE EURASIAN AND NORTH AMERICAN PLATES

RED SEA MID OCEAN RIDGE

LANDFORM RESULTING FROM DIVERGENT PLATE BOUNDARIES THAT PUSHED ARABIA AND EGYPT APART FORMING THE RED SEA

CONVERGENT PLATE BOUNDARY

PLACE WHERE TWO PLATES CONVERGE (COLLIDE)

AEGEAN SEA PLATE VOLCANIC ARC

LANDFORM LOCATED IN BETWEEN GREECE AND PELOPONNESE TO TURKEY RESULTING FROM CONVERGENT OCEANIC & CONTINENTA.L PLATE BOUNDARIES

ALEUTIAN ISLAND CHAIN

LANDFORM IN-BETWEEN KAMCHATKA AND ALASKA RESULTING FROM OCEAN VS OCEAN CONVERGENT PLATES

HIMALAYAS (MT. EVEREST)

LAND FORM RESULTING FROM CONTINENTAL CONVERGENT PLATES. PASSES THROUGH INDIA, PAKISTAN, AFGHANISTAN, CHINA, BHUTAN, AND NEPAL

SUBDUCTION ZONE

PLACE WHERE TWO PLATES COME TOGETHER, ONE SINKING BENEATH THE OTHER BACK INTO THE MANTLE

DEEP OCEAN TRENCH

LONG, NARROW, STEEP-SIDED DEPRESSION IN THE OCEAN BOTTOM THAT FORM WHEN ONE PLATE SUBDUCTS UNDER ANOTHER

MARIANA TRENCH

LANDFORM RESULTING FROM SUBDUCTION AND CONVERGENT OCEAN PLATE BOUNDARIES. LOCATED IN NORTH PACIFIC OCEAN EAST OF THE MARIANA ISLANDS.

TRANSFORM PLATE BOUNDARY

TWO PLATES SLIDE PAST EACH OTHER

EARTHQUAKES

RESULTING EVENT FROM A TRANSFORM BOUNDARY WHERE 2 PLATES SLIDE PAST EACH OTHER

SAN ANDREAS FAULT

LANDFORM RESULTING FROM A TRANSFORM PLATE BOUNDARY. LOCATED IN THE EAST SIDE OF CALIFORNIA.
