Across
- 3. when tectonic plates move apart, this is the type of interaction
- 4. the crust of the Earth is broken up into this, and they move very slowly in different ways
- 5. the height of a wave; how tall it is and how much energy it carries
- 7. molten rock that forms lava & igneous rocks when it flows from the upper mantle
- 8. these exciting features occur at boundaries that create space for magma to emerge and erupt from the crust
- 10. property describing how much matter is "packed" into a certain volume; or the ratio between mass and volume
- 14. these are formed wherever two plates interact in various ways
- 16. a more dense tectonic plate that is under the sea
- 17. least dense, thinnest, rigid layer of Earth
- 19. this "sphere" contains the crust and upper mantle and all their interactions
- 21. the least dense kind of plate that is under land
- 23. this happens when one plate goes underneath another plate
- 24. the number of wave forms in a given period of time
Down
- 1. when tectonic plates come together, this interaction occurs
- 2. thickest, "gooey" layer where convection currents affect plate movement
- 6. the distance between two wave forms
- 9. very dense, very hot, solid layer; contains Fe and Ni
- 11. how fast something is
- 12. the area that describes the "pull" or attractive force of a magnet
- 13. a (very familiar!)hard, solid combination of minerals produced from the cycle of composition and breaking down of the lithospher
- 15. liquid, metallic layer that surrounds the solid center
- 18. these "folded" features are formed at continental convergent boundaries
- 20. trembling, shaking events that occur due to seismic waves
- 22. how heat moves in a liquid or gas
