Across
- 4. waves - A back-and-fourth wave of energy released in an earthquake that causes back-and-forth vibrations of rocks in the same direction in the waves move.
- 8. - The action of the edge of one section of the Earth’s crust sliding below the edge of another section.
- 9. - The amount of energy released during an earthquake.
- 10. waves - An earthquake wave that travels through rock and vibrates at right angles to the direction of travel.
- 13. - The point on the Earth’s surface directly above an earthquake’s focus.
- 14. - The outer, solid part of the Earth, including the crust and the upper part of the mantle.
Down
- 1. waves - A vibration that radiates out from the focus of an earthquake.
- 2. boundary - A boundary where tectonic plates slide past each other.
- 3. - Landmass that existed about 225 million years ago and slowly split apart to form all of today’s continents.
- 5. - a linear zone where the Earth's crust and lithosphere are being pulled apart.
- 6. - A crack in the Earth’s crust along which earthquakes can happen.
- 7. boundary - A place where two plates of the Earth’s crust are moving towards each other.
- 11. boundary - A place where two plates of the Earth’s crust are moving away from each other.
- 12. Plate - One of the large, rigid pieces of rock that make up the Earth’s crust.
- 15. waves - One of the wavelike vibrations during an earthquake that causes much of the structural damage.
