Plate Tectonics
Across
- 2. known as lateral slipping plate movement
- 3. place where two tectonic plates are moving toward each other and colliding
- 4. Earth's lithosphere is divided into about 12 large plates and several small ones that float on and travel independently over the asthenosphere
- 5. the transfer of heat by the movement of large groups of particles from one place to another
- 6. developed in the 1960's
- 10. deep rift valley formed by the divergent boundary
- 11. downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate
- 12. high-energy wave caused by an earthquake, volcano, landslide or other natural event
- 13. sudden and violent shaking of the ground
Down
- 1. the movement of two oceanic plates away from each other
- 2. parts of the Earth's crust slowly drift atop a liquid core
- 7. also a divergent boundary
- 8. example of divergent but just where it's located
- 9. deepest feature of the ocean, plunging deep below the seafloor
