  2. Ice crystals grow on a window pane on a cold winter night.
  3. Fog dissipates as the Sun rises on a fall morning.
  4. Clouds develop over a mountain range on a warm spring day.

Under which of the following conditions is advection fog most likely to form?
  1. Cold air becomes trapped beneath a layer of warmer air.
  2. Hot dry air in contact with the surface cools after sunset.
  3. Cool moist air warms as it flows down a mountain side.
  4. Warm moist air flows over cold ocean water.

The psychrometer is based on which of the following principles?
  1. Relative humidity can be calculated by comparing the evaporative cooling that occurs in a particular location to the air temperature.
  2. The apparent temperature can be determined by comparing the actual temperature in a location with the relative humidity.
  3. The density of an air mass can be calculated by comparing the molecular weight of dry air to the molecular weight of the actual air.
  4. The adiabatic cooling of an air mass can be determined by comparing the actual pressure in a location to the theoretical sea-level pressure.

Climatologists have used computer models to investigate possible consequences of increased average global temperatures on various Earth systems. According to the models, which of the following changes in an Earth system is likely to occur in association with an increase in average global temperatures? 
  1. Regions prone to drought will become drier, due to longer periods without adequate rainfall.
  2. Jet stream winds will shift position more frequently, causing rapid changes in weather conditions.
  3. Hurricanes will become less common in tropical areas, due to a strengthening of the Coriolis effect.
  4. El Niño events will occur at longer intervals, causing anomalous weather conditions to last longer.

  1. Acidic liquids and gases generated by fixed sources.
  2. Fragments of natural substances visible to the unaided eye.
  3. Droplets and solids small enough to be suspended in the air.
  4. Heat-trapping chemicals that absorb infrared energy.
