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
