1. Proximity to bodies of water greatly affects an area's patterns of air temperature, because land heats and
cools more rapidly than water. Which reason does NOT explain why land heats and cools more rapidly than
water?
a) Evaporation from water is greater than evaporation from land.
b) Water has a much higher specific heat than land does.
c) The albedo of snow and ice covered land surfaces is higher than that of water.
d) Land surfaces are opaque, while water surfaces are transparent.
2. Which measures are compared when calculating relative humidity?
a) the water vapor content of the air and the temperature to which the air would have to be cooled to reach
saturation
b) the temperature of the air and its water vapor content
c) the quantity of water in the air and the mass of the air
d) the actual water vapor content of the air and its potential water vapor content at a given temperature
3. Adiabatic temperature changes result from what process?
a) compressing or expanding of air
b) particles in air changing state
c) absorption of heat reflected off Earth's surface
d) solar radiation
4. The approach of a storm system is often characterized by which conditions?
a) increasing atmospheric pressure and increasing temperature
b) decreasing atmospheric pressure and increasing wind speed
c) decreasing atmospheric pressure and decreasing wind speed
d) decreasing temperature and decreasing wind speed
5. A front is a region where two air masses impact each other. When a warm air mass is advancing toward a
cold air mass and pushing it back, which type of front occurs?
a) stationary
b) occluded
c) warm
d) cold

6. What kind of weather conditions do low pressure areas tend to experience?
a) cold weather and snow
b) cloudy conditions and precipitation
c) dry air and high temperatures
d) clear skies and fair weather
7. Of the factors that determine direction and speed of wind, which one affects surface winds but not upper air winds?
a) Coriolis effect
b) solar radiation
c) friction
d) pressure gradient
8. The image below is an example of a weather station model, a symbol used on weather maps to convey
several pieces of information about the weather in an area. Which conditions match those indicated in this
weather station model? Insert Art Spec[eart001_art01.doc] [Weather station model showing 21 25 mph
o
winds from northeast, pressure 138, temperature 76 F, and 100% cloud cover.]
a) 76 mph wind from the southwest, 100% cloud cover, 21 25 millibars atmospheric pressure,
o
temperature of 138 F
b) 76 mph wind from the northeast, 100% cloud cover, 138 millibars atmospheric pressure, temperature
o
of 21 25 F
c) 21 25 mph wind from the southwest, 100% cloud cover, 76 millibars atmospheric pressure,
o
temperature of 138 F

9. A psychrometer is used to measure humidity by showing the difference between temperatures from a dry
bulb and a wet bulb. How is this difference useful in indicating humidity?
a) The wet bulb shows the temperature of the water vapor in the air, and the dry bulb shows the
temperature of the other gases. By comparing the two temperatures, the saturation level of the air can be
determined.
b) The wet bulb measures how much water is in the air directly, and the temperature difference between it
and the dry bulb shows relative humidity.
c) The difference indicates how much water readily evaporates into the air, which correlates to the
saturation level (or humidity) of the air.
d) The difference shows the temperatures of air and water. The specific heat of these two fluids can be
used to find the saturation level.
10. What is a disadvantage of using satellites to track weather systems?
a) Satellites do not work at night.
b) Satellites cannot gather certain information about ground conditions.
c) There are very few satellites in operation.
d) Satellites take a very long time to create images and transmit them to Earth.
