Earth's Systems Vocab.

2. Move side to side through ONLY solids
4. No longer in existence
8. Occurs when divergent plates seperate
11. Boundary where tectonic plates slide past each other
12. Form at convergent boundaries where one plate subducts under another, and magma underground is pushed upward
14. The lower part of the Earth's mantle, Below the Asthenosphere
15. Forms under extreme heat and pressure, Appears twisted
17. The solid, outermost layer of the earth, lying above the mantle
20. The movement caused within a fluid when the hotter less dense material rises, and colder, denser material sinks
21. Boundary where tectonic plates collide
22. The study of Earth
23. Below the lithosphere. Hotter and more fluid part of the mantle
25. heat,pressure,cooling,melting,etc.
27. Petroluem, Natural Gas, Coal
29. The layer that lies of the earths crust crust and core. The majority of Earth's mass is in this layer
30. Boundary where tectonic plates divide
31. Forms when molten rock crystallizes and solidifies

1. Compress or squeeze through solids and liquids
3. The study of earthquakes
5. A tool that measures/records details of earthquakes
6. Still in existence
7. The outer part of the earth. Includes the crust and upper mantle
9. Group of animals that occupy an area
10. When magma flows through a crack in the middle of tectonic plate, and not at a plate boundary. Hawaiian islands were formed this way
13. water held underground in the soil
16. The innermost layer of the earth. Divided into 2 parts, liquid outer and solid inner
18. Large pieces of lithosphere that the ocean and continents rest on
19. The supercontinent that existed before continents seperated
24. When a sudden release of energy in the lithosphere creates seismic waves
26. A solid inorganic material found in nature
28. Forms from pre-existing rock and fossils
