| Question | Answer |
|---|---|
| Lithospheric Plate | one of the pieces of Earth's rocky crust that rests and moves on the semi-liquid mantle |
| Convergent Boundary | formed where two sections of Earth's crust are colliding (Hint: Collide) |
| Divergent Boundary | forms where lithospheric plates are moving away from each other (Hint: Divide) |
| Transform Boundary | boundary between two lithospheric plates where the plates are sliding past each other (Hint: Slide) |
| Plate Tectonics | theory that describes and explains the way that continents separated into today's land masses from one large land mass (Pangea). |
| Fossil | remains, impression, track, or other evidence of ancient organisms |
| Mantle | a layer of Earth's surface, lying just below the crust and above the inner core |
| Convection Current | Uneven heating causes material in the mantle to constantly ans slowly rise and fall |
| Continental Crust | less dense rocky material that makes up continents |
| Oceanic Crust | more dense portion of Earth's crust that lies beneath the oceans |
| Mid-Ocean Ridge | undersea mountain range that forms where two parts of Earth's crust are pushing apart (diverging plate boundary) |
| Subduction | the process in which one lithospheric plate slides under another; occurs at converging plate boundaries |
| Faults | crack within Earth's rocky crust, where rock has been fractured, and where rocks move past each other |
| Earthquake | energy travelling as waves passing through Earth, caused by sudden shift along a fault line, or by volcanic activity |
| Uplift | The lifting of land by forces in Earth's crust |
| Volcano | hill or mountain formed by material that erupts onto Earth's surface; caused by action of magma below the surface |
| weathering | the process by which water, wind, and ice wear down rocks. |
| sediment | fragments of weathered rock |
| erosion | the movement of sediment by wind, water, ice, or gravity |
| deposition | the process by which wind, water, and gravity leave eroded sediments in new locations |
| rock cycle | Earth's rocks change from one type into another over time due to various Earth processes. |
| igneous rock | formed when lava or magma cools and solidifies. |
| lava | molten rock or magma that has reached the Earth's surface, rapid cooling, small crystals. |
| magma | melted or molten rock material under the Earth's surface, cools slowly, larger crystals. |
| metamorphic rock | formed deep underground where heat and pressure cause existing rocks to be changed |
| heat and pressure | changing variables due to weight of overlying rocks, forming metamorphic rock. |
| sedimentary rock | rocks form when particles of other rocks are deposited in layers and are compacted and cemented together. |
| compaction | occurs when rock particles are pressed together or packed down by gravity and overlying rocks. |
| cementation | occurs when compacted sediments stick together and turn into rock. |
