| Convergent Boundaries Definition:In plate tectonics, a convergent boundary, also known as a destructive plate boundary, is a region of active deformation where two or more tectonic plates or fragments of the lithosphere are near the end of their life cycle. | Convergent boundaries form trenches. |
| Divergent Boundaries Definition:In plate tectonics, a divergent boundary or divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from each other. | Divergent boundaries can cause earthquakes and make volcanoes. |
| Transform Boundary Definition:Transform boundaries are places where plates slide sideways past each other. At transform boundaries lithosphere is neither created nor destroyed. | The San Andreas fault is a transform boundary. |
| Subduction Zone Definition:A subduction zone is the biggest crash scene on Earth. These boundaries mark the collision between two of the planet's tectonic plates. | Subduction zones create some of the biggest earthquakes. |
| Rift Valley Definition:A large elongated depression with steep walls formed by the downward displacement of a block of the earth's surface between nearly parallel faults or fault systems | There is a rift valley in east africa. |
| Mid Ocean Ridge Definition: A mid-ocean ridge is an underwater mountain system formed by plate tectonics. | Star fishes and crabs live in mid ocean ridges. |
| Trench Definition:Trenches form when one tectonic plate slides beneath another plate at a subduction zone. | The Mariana Trench and the Aleutian Trench are two of the best known trenches. |
| Volcano Definition:A mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapor, and gas are being or have been erupted from the earth's crust. | The state of Hawaii was created by volcano eruptions. |
