Question: Mercury is 13.6 times heavier than water. If atmospheric pressure raises a column of mercury in a barometer about 30 inches (760 mm), how tall would a water barometer have to be?

Possible Answers:

  1. 34 feet
  2. 24 feet
  3. 13.6 feet
  4. 2 feet

Answer: A, Because 13.6 x 30 in (760 mm) = 408 in (10,336 mm), and 408 in ÷ 12 in = 34 feet, a water barometer column would have to be at least 34 feet (10 m) tall.


Question: Water vapor will condense from air when the air is

Possible Answers:

  1. Saturated
  2. Dry
  3. Humid
  4. Cold

Answer: A, Air is saturated when it can hold no more water vapor, so that's when water begins to condense (turn back into liquid water).

Possible Answers:

  1. A heat wave
  2. A thunderstorm
  3. A snowstorm
  4. A hurricane

Answer: B, Cumulonimbus clouds usually mean a thunderstorm is on the way.


Question: The boundary between two different air masses is called a

Possible Answers:

  1. Isobar
  2. Isotherm
  3. Air mass
  4. Front

Answer: D, As on a battlefield, where two different kinds of air masses meet (say, one cold and dry, the other warm and humid) is called a front.


Question: In experiments called cloud seeding, what material have humans dropped or shot into a cloud in order to increase the likelihood of rain?

Possible Answers:

  1. Silver iodide particles
  2. Sand
  3. Glass beads
  4. Dust

Answer: A, Silver iodide particles have been used to seed clouds.


Question: Meteorologists use information from all EXCEPT the following sources in making weather forecasts:

Possible Answers:

  1. Radar
  2. Satellites
  3. Weather stations
  4. Seismometers

Answer: D, Radar, satellites, and weather stations all provide information on weather. Seismometers measure earthquakes.


Question: The orbit of the newest Polar-orbiting Operational Environmental Satellite (POES) is at what altitude above Earth's surface?

Possible Answers:

  1. About 5080 km (3156 miles)
  2. About 870 km (540 miles)
  3. About 70 km (43 miles)
  4. About 2550 km (1584 miles)

Answer: B, The POES orbit is about 870 km (540 miles) above Earth's surface.


Question: Which of the following cloud types generally reaches the highest altitude?

Possible Answers:

  1. Cirrocumulus
  2. Cumulonimbus
  3. Altostratus
  4. Cumulus

Answer: B, Cumulonimbus clouds can sometimes reach up to 18 kilometers (over 11 miles). No other types of clouds are found that high in the atmosphere.


Question: If the actual amount of water vapor in the air remains the same, but the temperature of the air goes up, the relative humidity will

Possible Answers:

  1. Go up
  2. Go down
  3. Stay the same
  4. Evaporate

Answer: B, The relative humidity will go down, because warm air holds more water vapor than cooler air.


Question: An important greenhouse gas that humans are adding to the atmosphere is

Possible Answers:

  1. Helium
  2. Hydrogen
  3. Oxygen
  4. Carbon dioxide

Answer: Carbon dioxide levels are only about 368 parts per million of air, but it is the most significant greenhouse gas. Tiny changes have big effects.


Question: The latitude that receives the most direct rays of the sun year-round is

Possible Answers:

  1. 60° N
  2. 90°
  3. 30° S

Answer: D, The equator is at latitude 0°, which gets the most direct rays of the Sun year round.


Question: How fast must the winds be blowing inside a tropical storm for it to be "upgraded" to a hurricane?

Possible Answers:

  1. 35 mph (56 km/h)
  2. 150 mph (240 km/h)
  3. 74 mph (119 km/h)
  4. 99 mph (160 km/h)

Answer: C, By definition, to be called a hurricane, a storm must have winds of at least 74 mph (119 km/h).


Question: The GOES satellites keep an eye on the weather from their geostationary orbits, which are at an altitude how high above the equator?

Possible Answers:

  1. 200 miles (320 km)
  2. 22,300 miles (36,000 km)
  3. 1500 miles (2400 km)
  4. 950 miles (1500 km)

Answer: B, The geostationary orbits of the GOES are at about 22,300 miles (36,000 km) above Earth's surface, at the equator.


Question: True or False: In January, Earth is farthest from the Sun.

Answer: False, in January, Earth is at its closest point to the Sun. It is winter in the Northern Hemisphere because the North Pole is tilted away from the Sun.


Question: True or False: Latitude has much more affect on climate than does longitude.

Answer: True, latitude is a measure of distance from the equator. The higher a location's latitude (whether north or south), the less directly the Sun shines on it.


Question: True or False: Dallas, Texas, at latitude 33°N, get less solar radiation than does San Francisco at latitude 37° N.

Answer: False, the lower the latitude number, the more solar radiation, or sunshine, the location receives. (The equator is latitude 0° so gets the most.)


Question: True or False: The windward side of a mountain range generally gets more rain than does the leeward side.

Answer: True, the windward side faces the prevailing winds, so creates air turbulence and becomes an obstacle for clouds to "stack up" against.
