Earth Science

2. core- mostly solid iron, at tremendous temperature and pressure.
3. plate boundaries that slide in opposite directions.
6. are used to measure seismic wave energy.
8. is the shaking of the Earth's surface resulting from the release of accumulated caused by the movement of tectonic plates.
10. is a very large sea wave produced when an earthquake occurs underwater.
11. core- composed of liquid iron and nickel.
13. is the crust and upper portion of the upper mantle.
14. plates- make up the lithosphere, which floats on the asthenosphere.
15. are openings in Earth's surface, that, when active, spew out gases, chunks of rock, and melted rock.

1. plate boundaries that come together.
4. is the point on Earth's surface directly above the focus.
5. is the molten layer of the upper mantle.
7. thickest layer, mostly solid except for upper mantle being able to flow like thick toothpaste.
9. is the action of one plate pushing below another.
12. is an area where molten rock rises to Earth's surface.
