| Question | Answer |
| Alfred Wegner's theory that the continents slowly moved over Earth's surface to their current locations. | CONTINENTAL DRIFT |
| Earth's crust and upper mantle are broken into sections that continents and ocean floors are carried on. | PLATES |
| Two plates SLIP past each other (earthquakes can occur). | TRANSFORM BOUNDARY |
| An underwater mountain chain that extends into all of the oceans on Earth. | MID-OCEAN RIDGE |
| Solid layer of Earth made of the crust and part of the upper mantle. | LITHOSPHERE |
| The plates of the lithosphere float and move around on the _____________, which is made of solid rock that flows like a thick liquid. | ASTHENOSPHERE |
| Old crust is pushed downward and sinks in the mantle. | SUBDUCTION |
| Deep crack running down the center of the Mid-Atlantic ridge. | RIFT VALLEY |
| Process that slowly adds new rock to the ocean floors. | SEA-FLOOR SPREADING |
| The movement of a gas or liquid caused by differences in temperature. | CONVECTION CURRENTS |
| Two plates move APART (rift valley and mid-ocean ridges form). | DIVERGENT BOUNDARY |
| All the continents that were once joined together in a supercontinent, meaning "all lands". | PANGAEA |
| Two plates COME TOGETHER or COLLIDE (volcanic mountain and deep-ocean trenches form). | CONVERGENT BOUNDARY |
| A device that scientists used to map the ocean floor. | SONAR |
