PRESENTATION OUTLINE
PLATE TECTONICS
MOVEABLE PIECES OF THE CRUST.
CONVECTION CURRENTS
IN THE MANTEL CAUSES PLATE MOVEMENT, BECAUSE OF DENSITY.
SLAB PULL
GRAVITY PULLS THE CRUST INTO THE EARTH.
SLAB PUSH
NEWLY FORMED CRUST PUSHES IT INWARDS.
DIVERGENT PLATE
BOUNDARIES. PLATES THAT MOVE APART.
A RIFT VALLEY FORMS
WHEN THIS OCCURS ON CONTINENTS.
A DEEP OCEAN RIFT VALLLEY
OCCURS WHEN THIS HAPPENS IN THE OCEAN.
CONVERGENT BOUNDARIES
WHEN TWO PLATES COLLIDE WITH EACH OTHER.
OCEAN VS CONTINENT
ITS CALLED SUBDUCTION, IT FORMS VOLCANOS AND A TRENCH
OCEAN VS OCEAN
THIS IS ALSO SUBDUCTION, IT CAUSES AN ISLAND BELT
CONTINENT VS CONTINENT
THESE FORM MOUNTINS LIKE THE HIMALAYANS.
SUBDUCTION ZONE
WHEN AN OCEAN CRUST IS SWALLOWED BY A CONTINENT CRUST.
DEEP OCEAN TRENCH
WHEN SUBDUCTION HAPPENS, A TRENCH FORMS
AN EXAMPLE WOULD BE
THE MARIANA TRENCH
TRANSFORM BOUNDARY
TWO PLATES SLIDE PAST EACH OTHER, NOT DAMAGING CRUST.
WHEN THIS HAPPENS
A FAULT FORMS, ONLY CAUSING EARTHQUAKES.
AN EXAMPLE:
THE SAN ANDREAS FAULT
