(please also write your name on the back)
1.
(5 pts) Energy transport by CONDUCTION CONVERGENCE DIVERGENCE CONVECTION can
only take place in liquids and gases, not in solids.
2.
(5 pts) The ______ carried by water vapor is released when the water vapor condenses and a cloud forms.
a. static electricity
b. kinetic energy
c. specific heat
d. latent heat energy
3.
(5 pts) On a day with a temperature of 40o F with 15 MPH winds, a thermometer would measure a
temperature GREATER LESS EQUAL than(to) 40o F.
4.
(5 pts) Wintertime low temperatures in a city on a coast are probably about the SAME COLDER than
WARMER than in a city located further inland. (both cities have the same altitude & latitude)
5.
(5 pts) When left in a warm room, a piece of dry ice will sublimate. What does this mean?
6.
(5 pts) Energy can be transported through empty space by
a. convection b. latent heat c. conduction d. all of these
e. none of these
7.
(5 pts) Wien’s Law says that if an object warms the _______ will decrease.
a. speed of propagation
b. wavelength of peak emission
c. radiative equilibrium temperature
d. intensity of emitted radiation
8.
(10 pts) The smallest change in temperature (ΔT) occurs when you add energy to an object with LARGE
SMALL mass and LARGE SMALL specific heat.
9.
(5 pts) A measurement of air temperature would give you a pretty good idea of the air molecule's
a. density
b. thermal conductivity
c. latent heat
d. specific heat
e. kinetic energy
10.
(10 pts) Compared to infrared light, visible light has LONGER SHORTER wavelength and is a LESS
MORE energetic form of EM radiation.
11.
(5 pts) The surface of the earth is negatively charged. Would the electric
field in the air above the ground point UPWARD or DOWNWARD?
12.
(5 pts) Which one of the following would not be associated with a surface center of low pressure?

13.
(5 pts) The wavelength of peak emission from an ordinary tungsten bulb is 1.0 micrometers (µm). Is this
VISIBLE, INFRARED, or ULTRAVIOLET light?
14.
(10 pts) The isobars shown on the map at right are contours of
DENSITY PRESSURE ALTITUDE TEMPERATURE. Would
the fastest winds be found on the RIGHT or LEFT side of the map?
Name_________________________________________
15.
(10 pts) An upper level TROUGH RIDGE is shown on the map
at right. The air below Point A is probably COLDER WARMER
than normal.
16.
(5 pts) Micrometers (µm) are units of WAVELENGTH SPEED ENERGY FREQUENCY.
17.
(10 pts) The air behind a cold front is normally COLDER WARMER and DRIER MOISTER
than ahead of a cold front.
18.
(15 pts) A COLD WARM front is shown at right. Is the front moving AWAY from
or TOWARD Point A? Is the air at Point A WARMER or COLDER than at Point B?
19.
(10 pts) Air expands when it SINKS RISES. Expanding air COOLS WARMS.
