MORGAN LARICK 2ND PERIOD

PIECES OF EARTHS LITHOSPHERE ARE IN CONSTANT, SLOW MOTION, DRIVEN BY CONVECTION CURRENTS IN THE MANTLE

THE TRANSFER OF HEAT BY THE MASS MOVEMENT OF HEATED PARTICLES INTO AN AREA OF COOLER FLUID

GRAVITY PULLING ON THE PLATES IN THE SUBDUCTION ZONES ALSO HELPS MOVE THEM. (SLAB PULL)

NEW CRUST FORMING PUSHES THE TECTONIC PLATES APART (RIDGE PUSH)

A BOUNDARY WHERE PLATES ARE MOVING APART.

THEY FORM A RIFT VALLEY WHEN THEY OCCUR ON LAND SUCH AS THE EAST AFRICAN RIFT.

IT FORMS AN OCEANIC RIDGE ON SEA SUCH AS THE MID ATLANTIC OCEANIC RIDGE

THE PLACE WHERE TWO PLATES CONVERGE

A DEEP OCEAN TRENCH FORMS SUCH AS THE CHILE-PERU TRENCH.

ISLANDIC ARCS OR VOLCANIC ARCS RESULT SUCH AS THE JAPAN ISLANDS

MOUNTAINS SUCH AS THE ANDES MOUNTAINS

A PLACE WHERE OCEAN CRUST SINKS BENEATH A DEEP OCEAN TRENCH AND BACK INTO THE MANTLE

ANY LONG NARROW, STEEP SIDED DEPRESSION IM THE OCEAN

MARIANNA'S TRENCH IS AN EXAMPLE

A PLACE WHERE TWO PLATES SLIP PAST EACH OTHER, MOVING IN OPPOSITE DIRECTIONS

EARTHQUAKES ARE A RESULTING EVENT.

AN EXAMPLE IS THE ALPINE FAULT OF NEW ZEALAND
