Across
  1. 2. Zone / The area of the Earth through which faulting occurred during an earthquake.
  2. 7. volcano / An active volcano that is in repose (quiescence) but is expected to erupt in the future.
  3. 8. Likes to chase mice
  4. 12. Man's best friend
  5. 13. Flying mammal
  6. 15. / An earthquake which follows a larger earthquake or main shock and originates in or near the rupture zone of the larger earthquake.
  7. 16. / A small tremor that commonly precedes a larger earthquake or main shock by seconds to weeks and that originates in or near the rupture zone of the larger earthquake.
  8. 17. Has a trunk
  9. 18. / lava fragments about 1 centimeter (about 1/2 inch) in diameter
  10. 20. cone / A steep-sided volcano formed by the explosive eruption of cinders that form around a vent.
  11. 21. / Molten rock containing liquids, crystals, and dissolved gases that forms within the upper part of the Earth's mantle and crust.
  12. 22. / A vent (opening) in the surface of the Earth through which magma erupts; it is also the landform that is constructed by the erupted material.

Down
  1. 1. boundary / The place where two or more plates in the Earth's crust meet.
  2. 3. / Shaking of the Earth caused by a sudden movement of rock beneath its surface.
  3. 4. / That point on the Earth's surface directly above the hypocenter of an earthquake.
  4. 5. rocks / Sometimes sedimentary and igneous rocks are subject to pressures so intense or heat so high that they are completely changed.
  5. 6. Large marsupial
  6. 9. / Volcanic rock (or lava) that characteristically is light in color, contains 69 percent silica or more, and is rich in potassium and sodium.
  7. 10. / An abrupt movement of soil and bedrock downhill in response to gravity.
  8. 11. / hat point within the Earth from which originates the first motion of an earthquake and its elastic waves; where the break in the fault actually occurred.
  9. 14. / One or a series of huge sea waves caused by earthquakes or other large-scale disturbance of the ocean floor.
  10. 19. Zone / A region in which earthquakes are known to occur.
