PRESENTATION OUTLINE
PLATE TECTONICS
THE LITHOSPHERE IS BROKEN INTO PIECES THAT MOVE.
CONVECTION CURRENTS
THE TRANSFER OF HEAT BY THE MOVEMENT OF HEATED PARTICLES.
SLAB PULL
THE PULL OF GRAVITY ON A PLATE THAT IS BEING SUBDUCTED.
RIDGE PUSH
NEW CRUST FORMS AND PUSHES OLDER CRUST OUT.
DIVERGENT PLATE BOUNDARY
WHERE TWO PLATES MOVE APART.
DIVERGENT EXAMPLE (LAND)
BETWEEN EURASIAN PLATE AND THE NORTH AMERICAN PLATE.
DIVERGENT EXAMPLE (SEA)
NORTH ATLANTIC PLATE SEPERATING ICELAND.
CONVERGENT PLATE BOUNDARY
WHERE TWO PLATES CRASH INTO EACH OTHER.
OCEAN VS. CONTINENT
A VOLCANO IS THE RESULT OF A OCEAN VS. CONTINENT
OCEAN VS. OCEAN
TRENCHES ARE THE RESULT OF AN OCEAN VS. OCEAN
CONTINENT VS. CONTINENT
THE HIMALAYAS ARE MOUNTAINS FROM CONTINENT VS. CONTINENT
SUBDUCTION ZONES
A COLLISION BETWEEN TWO TECTONIC PLATES WHERE ONE PLATE GOES BENEATH ANOTHER
DEEP OCEAN TRENCH
A DEEP DEPRESSION IN THE OCEAN FLOOR
DEEP OCEAN TRENCH
MARIANA TRENCH
TRANSFORM PLATE BOUNDRY
WHERE TWO PLATES SLIDE PAST EACHOTHER.
EFFECTS OF A TRANSFORM BOUNDRY
EARTHQUAKES ARE THE RESULT OF A TRANSFORM BOUNDARY.
TRANSFORM BOUNDRY EXAMPLE
SAN ANDREAS FAULT
