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.

    • 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.

    • 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.
