Tectonic plates

2. A massive, irregularly shaped slab of solid rock (lithosphere).
6. Where two plates slide horizontally past one another, often causing earthquakes.
8. a scientific theory stating earth's lithosphere is broken into moving plates that float on the semi-molten asthenosphere
9. Fault where rocks move horizontally past each other due to shear stress, common at transform boundaries
11. Fault caused by compression, where the hanging wall moves upward relative to the foot wall
13. The area where an oceanic plate sinks into the mantle, often forming deep ocean trenches.
15. deep, narrow depression in the ocean floor
16. Fault caused by tension, where the hanging wall moves downward as the crust is pulled apart, typical at divergent boundaries
18. location where hot mantle material rises in a fixed spot beneath a tectonic plates, forming volcanoes even away from plate boundaries
20. a large, uplifted landform created mainly at convergent boundaries when continental plates collide and push crust upward

1. Heat-driven currents in the mantle that move the plates.
3. The outermost layer, divided into continental (thicker, less dense) and oceanic (thinner, denser)
4. An underwater mountain range formed at divergent boundaries.
5. The soft, plastic layer of the upper mantle below the lithosphere that allows plates to move.
7. rising column of hot, buoyant mantle rock that feeds hotspot volcanoes. it metals crust above as it rises
10. an underwater mountain chain
12. The rigid outer layer of Earth, comprising the crust and upper mantle, broken into tectonic plates.
14. Where two plates move apart, often causing rifting or creating new crust.
17. A deep valley formed where two plates move apart, often on continents.
19. Where two plates collide. This leads to subduction (one plate sinks beneath another).
