| the theory that explains how large pieces of the lithosphere, called plates, move and change shape | plate tectonics |
| The plates of the lithosphere "__________" on top of the aesthenosphere | "float" |
| the process by which on lithospheric plate moves beneath another as a result of tectonic forces | subduction |
| What occurs when two plates move apart and create a gap between them? | divergent boundary |
| Mountain ranges at divergent boundaries in oceanic crust are known as ________________ | mid-oceanic ridges |
| Along the center of a mid-ocean ridge is a _________ __________, a narrow valley that forms where plates separate. | rift valley |
| T or F: New lithosphere is formed at divergent boundaries. | T |
| T or F: Older lithosphere is destroyed at convergent boundaries. | T |
| The process where the lithosphere of the oceanic plate, which is denser than the lithosphere of the continental plate, sinks into the mantle and drags the oceanic crust along with it is known as: | subduction |
| What 3 things are formed at subduction zones? | ocean trenches, mountains, and volcanoes |
| What is the name of the deepest trench located off the coast of Asia in the Pacific Ocean? | Mariana Trench |

| A rock that forms from other rocks as a result of intense heat, pressure, or chemical processes | metamorphic rock |
| What principle does this support: If there has been no disturbance in the position of the rock layers, the oldest will be on the bottom, and the youngest will be on the top | Principle of superposition |
