| Term | Definition |

| Divergent Boundaries | a boundary where two tectonic plates are moving AWAY FROM one another. |
| Convergent Boundaries | .Places where plates crash or crunch TOGETHER |
| Lithospshere | brittle uppermost shell of the earth, |
| Transform Fault Boundaries | one where the two plates slide against each other in a sideways - this pushing against one another sometimes creates a massive amounts of energy & occasionally this energy is released suddenly in the form of large earthquakes. |
| Normal Fault | a break in the earth's crust |
| Asthenosphere | a soft layer called over which the plates of the lithosphere glide |
| Plate Technoics | The theory that Earth's outermost layer, the lithosphere, is broken into 7 large, rigid pieces called plates - The plates are all moving in different directions and at different speeds |
| Sea Floor Spreading | theory that the ocean floors are spreading outward from vast underwater ridges. |
| Convection | the term that means when any liquid is heated it expands. |
| Volcanoes | create an almost infinite variety of landforms and terrain. However, geologists have noticed patterns when studying these different terrains, that allow them to group them into categories, based on how they are the same, and how they are different. These four landform types are called lava flows, volcanic peaks, calderas, and volcanic necks. |
| Ring Of Fire | -highly active volcanic area around the Pacific Ocean - More than half of the world's active volcanoes above sea level encircle the Pacific Ocean |
| Continental Drift | the theory that the world was made up of a single continent through most of geologic time. That continent eventually separated and drifted apart, forming into the seven continents we have today. T |
| Evidence of Continental Drift | The continents look as if they were pieces of a giant jigsaw puzzle that could fit together to make one giant super-continent. The bulge of Africa fits the shape of the coast of North America while Brazil fits along the coast of Africa beneath the bulge |
