Part 2

1 .Which of the following 4 spheres is made up of solid earth?

• biosphere
• lithosphere
• hydrosphere
• atmosphere

• Theencompasses all living organisms of the earth.
  • biosphere
  • lithosphere
  • hydrosphere
  • atmosphere
• Which of the following represents the lowest thermal layer of the atmosphere?
  • thermosphere
  • mesosphere
  • troposphere
  • stratosphere
• The highest atmospheric temperatures occur at:
  • the earth’s surface.
  • the troposphere.
  • the stratosphere.
  • top of the thermosphere.
• The relationship that temperatures decrease with altitude is found in which of the following atmospheric layers?
  • the troposphere only
  • troposphere and mesosphere
  • troposphere and thermosphere
  • stratosphere and mesosphere
• That an iron heated at one end will burn its holder exemplifies which of the following processes of energy transfer?
  • radiation
  • conduction
  • convection
  • all of the above
• Lines connecting places that have the same temperatures are termed:
  • contour-lines.
  • isotherms.
  • isobars.
  • isochrones.
• The ground can only radiate long wave radiation but the atmosphere radiates long wave radiation a. upwards, downwards
  • upwards, in all directions
  • downwards, upwards
  • upwards, at right angles to the upward flow
• 20 degrees C. is equivalent to degrees F.

c.-6.7

10.The distribution of atmospheric pressure is shown on maps by:

a. isoquants.

b. isobars.

• isohyets.
• contour lines.

1 1 .The solar constant:

• is highly variable.
• has a value of about 1370 W/m2
• is measured at the earth’s surface.
• is not affected by the earth’s atmosphere.

12.What properties of the earth’s atmospheric mass is accoutned for by the troposphere and the stratosphere?

• exactly 50%
• about 50%
• 75%
• 99%

1 3.The troposphere is shallower at the poles because of:

• the rotation of the earth.
• the low temperatures there.
• the absence of greenhouse gasses at high latitudes.
• none of the above.

• Why is it summer in N. Hemisphere in June?
  • Earth is closer tot the Sun in June.
  • Sun’s altitudes are highter and days are longer.
  • Sun sends out giant solar flares in June.
  • N. Hemisphere is tilted away from the Sun.
• The ocean, land and atmosphere all emit long wave radiation.
• As latitude increases away from the equator solar insolation value drops.
• The intensity of insolation having angle of inclination 30 0 is 50% of the direct vertical insolation.
• The highest diurnal temperature is reached at noon.
• Rural temperatures tend to be lower than urban because urban pavement reflects off much of the heat.
• Temperatures close to the ground are heavily influenced by the rapidity with which the surface both heats up during the day and cools at night.

TRUE/FALSE (15-21)

21.The March Equinox is much warmer than the September Equinox.

Part 3

• The major problem common to all maps is:
  • distance projection.
  • distortion.
  • lack of uniform scale.
  • none of these.
• The transformation of a geographic grid to a flat grid is:
  • cartography.
  • remote sensing. c. map projections. d. area enlargement.
• The projection is centered on the North or South Pole and displays the meridians as lines.
  • Mercator, curved
  • Goode, straight
  • conical, curved
  • Polar, radial
• A major difference between the solar year and the sidereal year is that solar year = 366.25 days whilst sidereal year = 365.26 days.
  • true
  • false.
• A cylinder is a developable surface.
  • true
  • false.
• When is it 9AM Friday CST at Memphis (90 0W), it is also 9AM Friday at Nashville (360 N 87 0W).
  • What is the local time at Nashville?
  • Why is local time = standard time at Memphis?
  • What is the local time at Little Rock (350 N 92 0W)?
• A flight from Tokyo (135 0 E) to Honolulu (150 0W) departs Tokyo Thursday 11:55PM and arrives Honolulu at 12:25PM (25 mins afternoon on the same day, i.e. 11.5 hours before departure). Compute the exact flight duration in hours and minutes.
• Read the following quotation and answer the questions below:
  • With suitable diagrams, prove the assertions.

Clearly state your work and reasoning.

“The sun’s altitude at local noon at 40•N latitude increases from 26.5 0 angle above the horizon at the winter solstice to a 73.5 0 angle above the horizon at the June solstice, a range of 47 0 .”

a.Clearly restate the 3 assertions in the quotation.

9.1t is June 21 in New York City ( lat 40.5 N ) what’s the noonday altitude of the sun ? Draw appropriate diagrams and show your reasoning
