  11. Earthquakes 1 • 500 points • ANSWER • c. move apart

  12. Earthquakes 2 • 100 points • If a major earthquake occurred in a populated inland area far from the shore, which of these would be LEAST likely to result? • damage to buildings and structures • tsunamis • loss of human lives • landslides

  13. Earthquakes 2 100 points ANSWER b. tsunamis

  14. Earthquakes 2 • 200 points • Buildings in areas where earthquakes happen frequently need to be seismically safe. Which of the following describes how a building in these areas should be built? • Buildings should be built so they will stand rigidly and not be able to sway • Buildings should have rubber moorings so they will sway instead of collapsing • Buildings should be built without reinforcing rods • Buildings should be built only on epicenters

  15. Earthquakes 2 • 200 points • ANSWER • b. Buildings should have rubber moorings so they will sway instead of collapsing
