| Direct Evidence of Earth's Interior | Rock samples |
| Indirect evidence of Earth's interior | seismic waves |
| Outer rock layer of the Earth | crust |
| The uppermost part of the mantle and crust | Lithosphere |
| The part of the mantle just below the lithosphere | asthenosphere |
| Pangaea | supercontinent |
| The idea that continents moved over Earth's surface | continental drift |
| He came up with the Pangaea theory | Wegener |
| These are all evidence that Wegener used to support his continental drift theory | land features, fossils, climate changes |
| Any trace of an ancient organism that has been preserved in rock | fossil |
| Ridges that wind beneath Earth's oceans | mid-ocean ridges |
| A device that bounces sound waves off underwater objects and records the echoes using those sound waves | Sonar |
| The name for the adding of new material to the ocean floor | sea-floor spreading |
| The man who proposed the sea-floor spreading idea | Hess |
| All of these are evidence that support the sea-floor spreading theory | molten eruptions, magentic stripes in ocean floor rock, and the ages of the rocks |
| This is where the oceanic crust bends downward | deep-ocean trenches |
| The process by which ocean floor sinks beneath a deep-ocean trench and back into the mantle | subduction |
| Pieces of Earth's lithosphere are in slow, constant motion driven by convection currents in the mantle | Theory of Plate Tectonics |
| These separate sections are what the lithosphere is broken into | plates |
| Breaks in Earth's crust where rocks have slipped past each other | faults |
| The place where two plates move apart from each other | Divergent boundary |
| The place where two plates come together | Convergent boundary |
| The place where two plates slip past each other, moving in opposite directions | Transform boundary |
