Science Plate Tectonics

4. where one edge of a plate is shoved below the edge of another
5. processes affecting the structure of earth's crust
6. rock slabs covering all of earth that divides earth's crust
8. plates that slide past each other
10. a small area with hotter temperature compared to the areas surrounding it
11. contains the crust and upper-most solid mantle. the outer layer of the earth
12. a type of igneous rock where magma from inside the earth flows out
14. plates that come together
15. caused by the earth's plates getting stuck at their edges
16. the outermost layer of the earth. made of rock
19. rock that is formed by molten rock cooling
20. theory that plates drift across the earth

1. the eruption of magma onto the earth's surface
2. plates that move away from each other
3. the layer below the lithosphere. denser and weaker than the lithosphere
7. the solid area of earth's interior between the core and the crust
9. a mountain with vents where lava, small rocks, and gas erupt through the earth's crust
13. a type of igneous rock where magma goes through older rock and solidifies beneath the Earth's surface
17. scientists who study the materials, processes, and history of earth
18. caused by seafloor movement. made by landslides, volcanic eruptions, earthquakes, etc.
