Dynamic Earth

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

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
