As a result of the Coriolis effect, wind currents tend to:
  1. Cool off as they converge and rise
  2. Flow in a straight path as they cross lines of longitude.
  3. Heat up as they diverge and sink.
  4. Curve as they flow over Earth's surface.

57.
An occluded front typically forms under which of the following conditions?
  1. A wedge of cool air between two warm fronts is forced upward as one of the fronts overtakes the other.
  2. A cold front catches up with a warm front, forcing warm air between the fronts upward and producing rain.
  3. A wedge of cold air between two warm fronts is forced upward as one of the fronts overtakes the other.
  4. A cold front overrides another cold front, trapping warm air at the surface and producing rain.

58.
Which of the following climate characteristics is the primary factor controlling the type of vegetation in the prairie of the upper Midwest?
  1. Strong seasonal winds
  2. Limited annual precipitation
  3. Regular grass fires
  4. Temperature extremes
See answer
59.
The polar jet stream typically has a major effect on the weather of the northern half of the United States. Which of the following is a major factor responsible for increasing the wind speed in the region of the polar jet stream?
  1. The geographical shift in temperature patterns associated with the different phases of the Arctic Oscillation.
  2. The gradual drop in pressure that occurs between the troposphere and stratosphere.
  3. The steep pressure gradient that exists between very cold northern air and warmer southern air.
  4. The seasonal change in atmospheric instability over temperate and tropical oceans.
See answer
60.
Fossil evidence indicates that tropical conditions once existed across the United States during the late Paleozoic era. This difference in the climate of North America today and the climate during the Paleozoic era was caused primarily by changes in the: 
  1. Concentration of oxygen in the atmosphere.
  2. Intensity of solar radiation.
  3. Directions in which ocean currents flow.
  4. Positions of the continents.
