unit 3 vocab
Across
- 1. A rock changed by extreme heat and pressure deep underground
- 5. The study of ancient magnetic fields preserved in rocks
- 6. the geological process where weathered rock, soil, and organic matter (sediments) are dropped or laid down in a new location
- 12. The creation of new oceanic crust at mid-ocean ridges that pushes older crust away
- 17. an area where two or more of Earth's tectonic plates move toward each other and collide
- 19. Earth's continents move horizontally relative to each other over geological time
- 20. the geological process where natural forces move weathered rock, soil, and sediment from one location on Earth's surface to another
Down
- 2. the process that breaks down rocks and minerals by changing their chemical composition
- 3. a fixed volcanic region on Earth fed by an anomalously hot mantle plume rising from deep within the planet
- 4. The physical deformation or change in shape of a rock caused by stress
- 7. The mechanical breakdown of rocks into smaller pieces without chemical changes
- 8. A plate boundary where two tectonic plates slide horizontally past each other.
- 9. a geological location where two tectonic plates move away from each other, allowing magma to rise from the mantle and create new crust
- 10. The physical force applied to a rock unit.
- 11. Rock formed when layers of sediment are compressed and cemented together
- 13. An area where one tectonic plate sinks beneath another plate into Earth's mantle
- 14. a crack or fracture in the Earth's crust where blocks of rock move past each other
- 15. solid rocks formed when hot, melted rock cools down and hardens
- 16. An underwater mountain chain where new oceanic crust forms
- 18. A lowland region formed where tectonic plates pull apart
