Plate Tectonics
Across
- 3. The strong lower part of the mantle.
- 5. The thin layer/surface of our planet that we live on.
- 6. The very hot and dense center of our planet made of iron and nickel.
- 8. The inner most layer of the earth made up of solid iron and nickel.
- 13. Properties that involve a reaction to an applied load.srength,ductiily,impact resistance,and toughness.
- 15. The only liquid layer of the planet that was discovered by seismic activity.
- 17. The nature of something's ingredients or constituents.
- 18. The plastic like layer of the mantle.
- 19. When 2 tectonic plates go the opposite direction of each other.
Down
- 1. A theory proposed by Alfred Wegner that pieces of the earths crust moves.
- 2. Broken up parts of the Lithosphere.
- 4. The process where new oceanic lithosphere forms as magma rises towards the earths surface and solidifies.
- 6. Tectonic plates that move which Alfred Wegener suggested and how that was Pangea was seperated.
- 7. Stress that occurs when the forces act to squeeze an object.
- 9. The sinking of regions of the Earth's crust to lower elevations.
- 10. The middle layer of the earth which is the largest and makes up 66 percent of the earth.
- 11. A large crack in the earth's surface.
- 12. When 2 plates slide past each other.
- 14. When 2 tectonic plates push together.
- 16. The layer that is composed of the crust and the upper mantle.
