Earth Processes

2. A molten mixture of rock-forming substances, gases, and water from the mantle
4. when one plate slides under the other
6. single landmass that broke apart 250 million years ago and gave rise to today's continents
10. magma that reaches the surface
11. this week was full of fun and dressing up
13. Sections of the Earth's crust that move due to convection currents.
15. an opening in the Earth's crust where magma reaches the surface
16. Earth's 'protective magnetic bubble' created by the movement of iron in the outer core
17. the color of Washington pride!
18. when plates collide and the land is deformed, can be volcanic or non-volcanic
20. when the plates slide past each other in opposite directions

1. Washington high schools mascot
3. hot dense center of Earth made of nickel and iron
5. when the plates are moving towards each other
7. when the plates are moving away from each other
8. the rocky outer layer of Earth
9. the middle layer of Earth (physical layer)
12. a thin area of the crust, far from the plate boundary, where there is volcanic activity
14. this happens in the mantle. the rising of hot magma and the sinking of cooler magma. helps drag the plates along.
19. a deep depression in the ocean. Happens at subduction zones
21. the middle layer of Earth. (chemical layer)
