| Term | Definition |
|---|---|
| Chemical Weathering — The breakdown of rocks caused by chemical reactions. | |
| Continental Drift Theory — The idea that continents slowly move across Earth’s surface over time. | |
| Convergent Boundary — A boundary where two tectonic plates move toward each other and collide. | |
| Deposition — When sediment is dropped and builds up in a new location. | |
| Divergent Boundary — A boundary where two tectonic plates move away from each other, creating new crust. | |
| Erosion — The movement of rock and sediment by water, wind, ice, or gravity. | |
| Fault (Tectonic) — A crack in Earth’s crust where rocks or plates can move. | |
| Hotspot (Tectonic) — A hot area deep inside Earth where magma rises and can create volcanoes. | |
| Igneous Rock — Rock that forms when melted rock, or magma, cools and hardens. | |
| Metamorphic Rock — Rock that changes because of heat and pressure. | |
| Mid-Ocean Ridge — An underwater mountain range where new ocean crust forms. | |
| Paleomagnetism — The study of Earth’s past magnetic field recorded in rocks. | |
| Physical Weathering — The breaking of rocks into smaller pieces without changing what they are made of. | |
| Rift Valley — A long, deep valley formed when tectonic plates move apart. | |
| Seafloor Spreading — The process where new ocean crust forms and spreads away from a mid-ocean ridge. | |
| Sedimentary Rock — Rock formed when layers of sediment build up, press together, and harden. | |
| Strain — The change in the shape or size of a rock caused by stress. | |
| Stress — A force that pushes, pulls, or squeezes rocks. | |
| Subduction Zone — An area where one tectonic plate sinks beneath another plate. | |
| Transform Boundary — A boundary where two tectonic plates slide past each other. | |
