EAPS 100 EXAM 3 QUESTIONS WITH
CORRECT ANSWERS
Which of the following regarding ocean currents and atmospheric stability is true? -
Answer- Cold currents promote stable atmospheric conditions and limited water vapor
capacity.
The weather system most likely to produce the strongest tornadoes is generally
associated with - Answer- cold fronts.
As the moisture-rich air approaches the mountain, it rises and cools, and water
molecules in the air combine to form small drops. The process where water vapor
becomes a liquid is called condensation. - Answer- Correctly complete the sentences
with the words provided.
On the far right of the figure, air descends and dries out, limiting the amount of
precipitation and forming a rain shadow. - Answer- Correctly complete the sentences
with the words provided.
On the left side of the figure, water evaporates from the oceans and rises into the
atmosphere. - Answer- Correctly complete the sentences with the words provided.
In this image from Tibet, water is expressed in a visible form through - Answer- clouds,
ice, and snow.
Fog can form through each of the following ways EXCEPT - Answer- decreasing the
moisture content of the air and increasing temperature.
For precipitation to occur, - Answer- buoyant forces keeping water droplets and ice
crystals suspended must be less than the force of gravity.
An example of a primary effect of drought: - Answer- drop in groundwater levels.
An important property of water is its ability to act as a good solvent. This could best be
explained by water's - Answer- polarity.
The specific humidity of air changes when there is a change in - Answer- the addition or
removal of water vapor.
Dew point measures - Answer- the temperature at which air is saturated with water
vapor.
, Variations in specific humidity vary primarily as a function of - Answer- latitude.
Why is the saturated adiabatic lapse rate less than the unsaturated adiabatic lapse
rate? - Answer- Release of latent heat warms the local environment.
A parcel of air at the surface is heated which expands the air and increases the parcel's
volume. If the same number of air molecules occupy the greater volume, density
decreases. The increase in volume results in lower pressure. What will happen to the air
surrounding this parcel? - Answer- Denser air flows in to replace the rising air.
With height, wind speed in the atmosphere would _______________. With depth, the
effect of wind on the water column would _________________. - Answer- increase;
decrease
In the Northern Hemisphere cold currents tend to flow from the ____________. In the
Southern Hemisphere warm currents tend to flow from the ________________. -
Answer- north; north
Where on the map is the center of high pressure influencing ocean currents with a
counterclockwise circulation? - Answer- D
In regard to sea surface temperature (SST), as one travels toward the poles SST -
Answer- decreases.
As a result of cold currents, July SST's are coldest - Answer- on the west coasts of
continents.
Hydrogen bonds in water form between the - Answer- hydrogen atom of one water
molecule and the oxygen atom of another water molecule.
At point __________ on this graph, the density of water begins to decrease. The
temperature at this point is _______. - Answer- D; 4°C
Once salt is dissolved in water the - Answer- positively charged sodium cation is
surrounded by the negative side of encircling water molecules.
Water's salinity can be increased by - Answer- ice freezing.
The dominant control in global sea surface temperature (SST) is - Answer- the supply of
solar insolation.
Subtropical waters are typically more saline than equatorial waters because of -
Answer- high evaporation, low precipitation.
The waters off the coast of Peru are normally - Answer- cold because of a current
bringing cold water from the south and upwelling conditions.
