Across
- 3. the physical layer of Earth that is below the asthenosphere
- 6. a place where two or more tectonic plates slide alongside each other formed by shear stress
- 10. ground movements that happen when blocks of rock move suddenly and release energy
- 11. a break in Earth's crust
- 13. the physical layer of Earth that is below the lithosphere, where tectonic plates float on top of
- 15. the outermost compositional layer of earth that is Earth's thin outer shell
- 16. a place where two or more tectonic plates move apart from each other caused by tension
- 17. outer layer of the core, liquid due to very high temperatures
- 19. a place where two or more tectonic plates move toward each other and collide caused by compression
- 20. a series of long waves that can travel across the ocean at very high sp
- 22. the process by which one tectonic plate is pulled under another
- 23. the compositional layer below the crust that is dense and has magnesium and iron
- 24. the center of the Earth, containing iron and nickel
Down
- 1. mineral sources that form along mid-ocean ridges
- 2. waves of energy that earthquakes release
- 4. the outermost physical layer of Earth
- 5. the process by which new sea-floor forms
- 7. the place within a fault that the Earthquake starts in
- 8. the energy of motion
- 9. directly above the focus on Earth's surface, where an Earthquake is strongest
- 12. any movement of matter that results from differences in density
- 14. theory that states that giant moving slabs in the lithosphere called tectonic plates that move
- 18. drift a hypothesis formed by Alfred Wegener that states that the Earth used to be one single land mass, and the continents drifted
- 21. the center of the Earth that is solid due to extreme amounts of pressure from other layers
