PRESENTATION OUTLINE

PLATE TECTONICS

THE LITHOSPHERE IS BROKEN UP INTO SMALL PLATES THAT ARE MOVING.

CONVECTION CURRENTS

THE CHANGE OF LIQUIDS DUE TO THEIR DENSITYS

SLAB PULL

WHEN GRAVITY PULLS A PLATE INTO THE MANTLE

RIDGE PUSH

WHEN THERE IS A DIVERGENT PLATE BOUNDRY AND LAVA FLOWS IN GAPS.

DIVERGENT PLATE BOUNDRY

WHEN THE TWO PLATES ARE PULLING APART FROM EACH OTHER

RIFT VALLEY

LANDFORM THAT RESULTS FROM A DIVERGENT PLATE BOUNDRY

MID OCEAN RIDGE

UNDERWATER LANDFORM THAT IS CAUSED BY DIVERGENT BOUNDRIES

CONVERGENT PLATE BOUNDRY

IT IS WHERE TWO PLATES COLLIDE WITH EACH OTHER

SUBDUCTION

WHEN TWO PLATES COLLIDE AND ONE SINKS BELOW THE OTHER.

SUBDUCTION (OCEAN VS. OCEAN)

A DEEP OCEAN TRENCH IS WHAT WOULD BE FORMED FROM SUBDUCTION

MOUNTAIN RANGE

SUBDUCTION ZONE

WHERE TWO PLATES COLLIDE AND ONE GOES UNDERNEATH.

DEEP OCEAN TRENCH

WHEN A PLATE IS SUBDUCTED IN THE OCEAN A DEEP TRENCH IS MADE

DEEP OCEAN TRENCH

THIS IS THE PUERTO RICO TRENCH

TRANSFORM PLATE BOUNDRY

WHEN TWO PLATES SLIDE PAST EACH OTHER

FAULT

FROMS WHEN TWO PLATES SLUDE PAST EACH OTHER

AN EXAMPLE OF A TRANSFORM BOUNDRY

IS THE SAN ANDREAS FAULT
