unit 3 vocab

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

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
