| boundary where deep ocean trenches are found | CONVERGENT |
| boundary where the mid-ocean ridge forms | DIVERGENT |
| famous strike-slip fault found in North America | SAN ANDREAS |

| landform associated with a convergent boundary involving oceanic crust | DEEP OCEAN TRENCH |
| landform associated with a continental-continental convergent boundary | NON-VOLCANIC MOUNTAIN RANGE |
| Pangaea contained all of Earth's ___ crust | CONTINENTAL |
| property of a plate's crust that determines how it interacts at plate boundaries | DENSITY |
| ___ form at convergent boundaries because oceanic crust melts in the process of subduction | VOLCANOES |
| location of the majority of Earth's active volcanoes | RING OF FIRE |
| the process of mountain building, volcanic activity and earthquakes all occur primarily at ___ ___ | PLATE BOUNDARIES |

| process associated with a continental-continental convergent boundary | MOUNTAIN BUILDING |
| geologic event associate with transform boundaries | EARTHQUAKES |
| geologic event associated with oceanic convergent boundaries | STRONG EARTHQUAKES |
| ocean that gradually is getting smaller due to its many convergent boundaries | PACIFIC OCEAN |
| landform associated with oceanic divergent boundary | MID-OCEAN RIDGE |
| theory that states Earth's crust is broken into plates that are slowly but constantly moving | THEORY OF PLATE TECTONICS |
| ocean that is gradually getting larger because it is not surrounded by convergent boundaries | ATLANTIC OCEAN |
| scientists discovered the boundaries of the plates by mapping ___ & ___ | EARTHQUAKES & VOLCANOES |
| the source of new oceanic crust in the process of sea-floor spreading | MOLTEN MATERIAL IN THE MANTLE |
| VOLCANIC MOUNTAINS FORM AT __ BOUNDARIES | DIVERGENT & CONVERGENT (continental-oceanic) |
| THE MIDOCEAN RIDGE FORMS AT __ BOUNDARIES | DIVERGENT |
| DEEP OCEAN TRENCHES FORM AT __ BOUNDARIES | CONVERGENT (continental-oceanic & oceanic-oceanic) |
| ISLAND ARCS FORM AT __ BOUNDARIES | CONVERGENT (oceanic-oceanic) |
| NON-VOLCANIC MOUNTAINS FORM AT __ BOUNDARIES | CONVERGENT (continental-continental) |
| VOLCANIC ACTIVITY OCCURS AT __ BOUNDARIES | DIVERGENT & CONVERGENT (continental-oceanic & oceanic-oceanic) |
| SEAFLOOR SPREADING OCCURS AT __ BOUNDARIES | DIVERGENT |
| EARTHQUAKES OCCUR AT __ BOUNDARIES | ALL (remember the earthquake mapping video?) |
| TENSION IS THE STRESS FORCE AT __ BOUNDARIES | DIVERGENT |
| SHEARINGIS THE STRESS FORCE AT __ BOUNDARIES | TRANSFORM |
| COMPRESSION IS THE STRESS FORCE AT __ BOUNDARIES | CONVERGENT |
| WHAT IS THE CAUSE OF PLATE MOVEMENT? | CONVECTION CURRENTS IN THE ASTHENOSPHERE |
| WHAT PROPERTY DETERMINES HOW PLATES INTERACT? | DENSITY (for example, oceanic crust sinks beneath continental crust at a convergent boundary) |
| WHICH CRUST IS THICKER? | CONTINENTAL |
| WHICH CRUST IS MORE DENSE? | OCEANIC |
