20 Although the polar regions radiate away more heat energy than they receive by insolation in the course of a year, they are prevented from becoming progressively colder each year by the
conduction of heat through the interior of the earth.
absorption of heat by snow and ice surfaces.
circulation of heat by the atmosphere and oceans.
storage of heat in the soil beneath the snow cover.
release of latent heat to the atmosphere when the polar ice melts.

21 The earth is tilted at an angle of 23 1/2 degrees. If the amount of tilt was decreased to 10 degrees, we would expect in middle latittudes
hotter summers and colder winters than at present.
cooler summers and milder winters than at present.
hotter summers and milder winters than at present.
cooler summers and colder winters than at present.
no appreciable change from present conditions.

22 Suppose you drive to and from work on a street that runs east to west. What time of the year would you most likely have the sun shining directly into your eyes while driving to work in the morning?
summer solstice
autumnal equinox
winter solstice
vernal equinox
both (b) and (d)

23 In middle latitudes in the Northern Hemisphere we can expect the day with the shortest number of daylight hours to be around
June 22
December 22
September 23
January 1
February 3

24 The earth is tilted at an angle of 23 1/2 degrees. If the amount of tilt were increased to 40 degrees, we would expect in middle latitudes
hotter summers and colder winters than at present
cooler summers and milder winters than at present
hotter summers and milder winters than at present
cooler summers and colder winters than at present
no appreciable change from present conditions

25 Solar insolation from middle latitudes is less in winter than in summer because
the sun's rays slant more and spread their energy over a larger area
the sun's rays are weakened by passing through a greater thickness of atmosphere
the cooler air lowers the intensity of solar radiation in winter
all of the above
only (a) and (b)

26 The main reason(s) for warm summers in middle latitudes is that:
The earth is closer to the sun in summer
The sun is higher in the sky and this causes more intense radition
The days are longer than in winter
all of the above
only (b) and (c)

27 The lowest tmperature is usually observed:
sunset
midnight
in the middle of the night
around sunrise
several hours after sunrise

28 During the afternoon, the greatest temperature differnece between the surface and the air in a Stevenson Screen occurs on a :
clear, calm afternoon
clear, windy afternoon
cloudy, calm afternoon
cloudy, windy afternoon

29 In summer, humid regions typically have ___________ diurnal (daily) temperature ranges and ___________ maximum tempertures then dry regions.
lower, lower
lower, higher
higher, lower
higher, higher

30 Which of the statements below is (are) true?
If you travel from Dallas to Superior in winter you will experience greater temperature change than if you made the same trip in July
Annual temperature ranges are higher in Des Moines than in New York (both 42oN)
If two cities have the same mean annual temperatures then their temperatures throughout the year are quite similar
All above
Only (a) and (b)

31 Deserts have a high duirnal temperature range because:
there is little water vapor in the air to absorb terrestrial radiation at night -- so minimum temps are low
the dry conditions result in higher daytime temps because latnet heat losses are low due to lack of moisture
sand has a high albedo
all of the above
Only (a) and (b)

32 The effect of urban heat production on the urban heat island is greatest:
In summer
In winter
No one season
