Chapter 12: Moisture, Clouds and Precipitation

1) ________ is an indication of how near the air is to saturation rather than the actual quantity of water vapor in the air.A) Mixing ratioB) Relative humidityC) Dew-point temperatureD) Adiabatic cooling

2) A 1-kilogram parcel of air is at 35°C and contains 7 grams of water vapor. What is the relative humidity?A) 20%B) 40%C) 50%D) 70%

3) Examine the figure. This flask contains 1 kilogram of dry air mixed with 20 grams of water vapor. It is at 25°C temperature. What would happen if its temperature was increased to 35°C?A) The relative humidity would decrease, triggering evaporation from the pool of liquid water at the bottom of the flask.B) The relative humidity would decrease, triggering condensation, and raising the level of the pool of liquid water at the bottom of the flask.C) The relative humidity would increase, triggering condensation, and raising the level of the pool of liquid water at the bottom of the flask.D) The relative humidity would increase, triggering evaporation from the pool of liquid water at the bottom of the flask.

4) How can condensation be triggered to form clouds or fog?A) Add sufficient water vapor to the air so that it reaches saturation.B) Cool the air to its dew point.C) Either of the above will work.D) Neither of the above will work.

5) Adiabatic temperature changes occur ________.A) when heat is addedB) when heat is subtractedC) when heat is neither added nor subtractedD) when water vapor is added

6) A fire extinguisher containing compressed CO2 is used to put out a fire. In spite of being close to the flames, the firefighter notices a white layer of "frost" forming on the exterior of the fire extinguisher can. What's going on?A) The gas in the extinguisher is expanding when released, cooling adiabatically.B) The gas in the extinguisher is cooling under higher pressure.C) The exterior temperature must be dropping.D) The fire is pulling heat from the surrounding air.

7) Examine the figure. Which process is illustrated?A) orographic liftingB) frontal wedgingC) adiabatic coolingD) convergence

Chapter 13: The Atmosphere in Motion

1) Which of the four lettered locations on this barometer would correspond to a hurricane (tropical cyclone)?A) AB) BC) CD) D

2) Because unequal heating of Earth's surface generates these pressure differences, ________ is/are the ultimate energy source for most wind.A) cavesB) hot springsC) solar radiationD) the greenhouse effect

3) Which of the four lettered locations on the map would have the highest pressure gradient (and thus, the highest potential for winds)?A) AB) BC) CD) D

4) You are getting ready to go for a hike on a summer day. You check the barograph and

Earth Science 11: Atmosphere Unit Test ReviewPage 4

discover that the pressure tendency has been rising for several hours. Based on this information, what gear should you be sure to pack for your hike?A) snowshoesB) sunscreenC) a rain jacketD) a helmet

5) The zone of subsiding dry air which encircles the globe near 30° latitude, north and south, is known as the ________.A) Hadley cellB) subtropical highC) trade windsD) polar front

6) In Eurasia, the land becomes cold in the winter and develops a seasonal high-pressure system from which surface flow is directed off the land. In the summer, in contrast, the opposite occurs: The landmasses are heated and develop a low-pressure cell, which permits air to flow onto the land. This "switch" in directions of airflow into or off of the continent gives rise to ________.A) the monsoonB) cyclonesC) the polar highD) easterlies and westerlies

7) Which of these factors influence the magnitude of the Coriolis force?A) wind speedB) latitudeC) wind directionD) both wind speed and latitude

8) This pressure zone is associated with abundant precipitation and warm temperatures.A) subtropical highB) equatorial lowC) subpolar lowD) anticyclone

10) On the basis of vegetation patterns,

Earth Science 11: Atmosphere Unit Test ReviewPage 5

cloud cover, and sea surface patterns (choppy or calm), identify the directions that the prevailing trade winds blow over the Hawaiian islands. Draw an arrow on this image to express your answer.

11) Examine the map showing air pressure in millibars. Compare and contrast what sorts of weather situations would you expect at sites "B" and "D" on the map.__________________________________
