Plate Tectonics

4. ‐ the solid outer part of Earth that includes the crust and upper mantle.
6. ‐ melted rock on Earth’s surface.
8. ‐A crack or fracture in Earth's crust where two tectonic plates grind past each other in a horizontal direction.
9. ‐ A trembling and shaking of the earth's surface resulting from the sudden release of energy in the crust.
11. Boundary ‐The boundary that occurs where two plates are pushing toward each other.
13. plate ‐ a large piece of the lithosphere that floats and moves on the asthenosphere.
17. ‐ the layer of Earth between the core and the crust
19. ‐ The name given to the super continent that existed more than 225 million years ago, in which the present‐day continents were joined together in one large landmass.
20. boundary ‐ an area where two or more tectonic plates meet.

1. Boundary ‐The boundary that occurs where two plates are moving apart from each other.
2. ‐ a straight line of travel where data is being collected.
3. ‐ a slowly flowing layer of solid and melted rock formed by heat and pressure
5. Core ‐The innermost layer of the earth, an extremely hot, solid sphere of mostly iron and nickel.
7. ‐ Hard and rigid, the earth's outermost and thinnest layer.
10. spot ‐ is formed when very hot rock rises from the mantle and erupts through Earth’s crust.
12. ‐ Made up of the crust and a tiny bit of the upper mantle
14. ‐ the outermost layer of Earth.
15. Core ‐ This layer of the earth lies between the mantle and the solid inner core.
16. ‐Molten rock that flows beneath the earth's surface and is made up of gases, liquids, and crystals.
18. ‐ This dense layer of the earth is made of hot, semisolid rock and is located directly below the crust.
