AND ANSWERS 100% CORRECT
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.
This diagram features a(n) - ANSWER-cyclone in the Southern Hemisphere.
In accordance with Charles's Law, a gas under constant pressure will ________ when
________. - ANSWER-expand; heated
Jet streams: - ANSWER-blow west to east in both hemispheres.
The dot on this map represents Missouri. Based on your knowledge of the anticyclone's
wind direction, how would temperatures change between 2/11/2012 and 2/13/2012? -
ANSWER-cooler then warmer
Global belts of prevailing winds are caused by - ANSWER-the higher spin velocity and
higher atmospheric solar heating at the equator.
We describe wind by the direction it is: - ANSWER-originating from.
On an air pressure map with closely spaced isobars, the pressure gradient will be
________ and the pressure gradient force will be ________. - ANSWER-steep; strong
Which of the following statements is true regarding high or low pressure for a parcel of
air at the surface? - ANSWER-lower temperature, higher density, cold air sinks, higher
pressure at surface
In accordance with the pressure gradient, air is: - ANSWER-more tightly packed in high
pressure zones and moves toward low pressure zones.
The Coriolis effect in the atmosphere is due to: - ANSWER-the atmosphere rotating
faster at the equator than at the poles.
Dynamic forcing of upper air currents will create: - ANSWER-upper air convergence at
A that results in surface high pressure.
Which of the following best describes air circulation at high latitudes? - ANSWER-Cold
dense air sinks at the poles, flows outward away from poles, and rises between 60 and
45 degrees latitude.
, If a gas cools under constant pressure, the molecules within it have ________ kinetic
energy (motions) and can therefore ________. - ANSWER-less; be packed into a
smaller volume
The molecular structure of water has an asymmetrical arrangement of hydrogen atoms
causing: - ANSWER-the hydrogen side of the water molecule to have a positive charge.
The specific humidity of air changes when there is a change in: - ANSWER-the amount
of water vapor in a parcel of air.
An important property of water is its ability to act as a good solvent. This is best
explained by water's: - ANSWER-polarity.
The rate at which saturated air cools with adiabatic ascent is: - ANSWER-variable
depending on temperature.
If a gas is heated to a higher temperature and the pressure does not change, the: -
ANSWER-density will decrease.
Pushing down on the sealed glass container causes the volume to ________ and the
pressure to ________. - ANSWER-decrease; increase
All of the following would contribute to destructive wildfires promoted by Santa Ana
winds except: - ANSWER-a sea breeze.
Which of the following statements is true regarding the relationship between air
pressure and altitude? - ANSWER-As one moves up in the atmosphere, pressure
decreases; as one moves closer to the earth's surface, pressure increases.
The Hadley cell is characterized by: - ANSWER-low pressure with rising air over the
equator, and high pressure with sinking air at 30°N and 30°S.
What location best represents a trough of low pressure? - ANSWER-D
