  1. The production of a commodity has been growing exponentially with time at a rate of 5% per year. The time required to QUADRUPLE the annual production at this growth rate is closest to: 5 years 14 years 20 years 28 years 50 years * The percentage growth rate value changes from year to year. *

  3. Although it is probably impossible to predict precisely when an earthquake will occur, one of the following features may indicate that an area is at high risk of a major earthquake: A seismic gap along an active fault zone aftershocks Ground subsidence Electrical storms Low levels of radon in wells

  5. We can sample rocks at the surface of the Earth to determine their density, but to place limits on the nature of materials deeper in the Earth, we need to determine the AVERAGE density of Earth. We can do that by studying the interaction of the Earth with the moon. In doing that determination, you would need all but one of the following. Which one don’t you need? The Earth’s moment of inertia The radius of the Earth The gravitational constant (G) The orbital velocity of the moon The distance from the Earth to the Moon

  13. As seismic energy waves travel deeper and deeper in the lower mantle of the Earth, the P-wave velocity increases with depth because: The compressibility modulus decreases with depth in the mantle The chemical composition of the mantle changes with depth The density increases with depth in the mantle The elasticity increases more rapidly than the density with increase in depth The lower mantle becomes more plastic
