Across
  1. 3. smaller earthquakes that occur in the same general area during the days to years following a larger event or "mainshock.
  2. 4. a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake.
  3. 6. A plate boundary where two plates move toward each other.
  4. 9. a transverse or longitudinal earthquake wave that travels through the interior of the earth
  5. 11. a current in a fluid that results from convection.
  6. 13. a German climatologist, geologist, geophysicist, meteorologist, and polar researcher.
  7. 15. an American geologist and a United States Navy officer in World War II who is considered one of the "founding fathers" of the unifying theory of plate tectonics.
  8. 16. A rigid layer made up of the uppermost part of the mantle and the crust.
  9. 17. waves that oscillate the ground perpendicular to the direction of wave travel
  10. 18. place inside Earth's crust where an earthquake originates.
  11. 20. a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action.
  12. 21. the vibration of the rock is in the direction of propagation. these waves travel fastest and are the first to arrive from the earthquake
  13. 22. loosely packed, water-logged sediments at or near the ground surface lose their strength in response to strong ground shaking.
  14. 23. a mild tremor preceding the violent shaking movement of an earthquake.
Down
  1. 1. A zone of hot, partly melted rock that flows and can be deformed like soft plastic.
  2. 2. A plate boundary where two plates move away from each other.
  3. 5. a record produced by a seismograph.
  4. 7. the continent we now know as North America was contiguous with Africa, South America, and Europe.
  5. 8. caused by the sudden movement of materials within the Earth, such as slip along a fault during an earthquake.
  6. 10. an area where tectonic plates move sideways past each other
  7. 12. waves travel more slowly through Earth material at the planet's surface and are predominantly lower frequency than body waves.
  8. 14. the branch of science concerned with earthquakes and related phenomena.
  9. 19. study shock waves created by earthquakes and volcanic activity. They also work in oil, gas and minerals exploration.
  10. 20. the point on the earth's surface vertically above the focus of an earthquake.
