ACING EAPS 100, EXAM 3 WITH ESSENTIAL A+
QUESTIONS AND ANSWERS
A gas under constant pressure will ____________ when ____________.
expand; heated
A gas under constant temperature will ____________ in volume when the pressure is
____________.
decrease; increase
Heat is applied to a container. The molecules inside the container become
more energetic; pressure increases.
Pushing down on the sealed glass container causes
decreased volume, pressure increases.
Which of the following statements is true regarding the relationship between air pressure
and altitude?
As one moves up in the atmosphere, pressure decreases; as one moves closer to the earth's
surface, pressure increases.
In accordance with the pressure gradient,
air is more tightly packed in high pressure zones and moves toward low pressure zones.
Wind is the movement of air. Wind direction is conveyed as the direction OUT of which, or
from which, the wind is blowing. Wind direction can be described as north, south, east, or
west, or by azimuth, the degrees clockwise from north. Drag the correct azimuth to the
correct direction.
The pressure cells viewed below are influenced by the pressure-gradient force (which starts
air moving), the Coriolis effect, and, if close to Earth's surface, friction with the surface. The
results of these interactions produce distinctive and familiar patterns of wind and circulation
of air around areas of high and low pressure. Drag the correct term to the correct diagram.
(11-8)
Insolation warms equatorial regions more than the poles, setting up pressure differences that
drive large-scale atmospheric motion. Once set in motion, the moving air is acted upon by the
Coriolis effect and by friction with Earth's surface. These factors combine to produce curving
patterns of circulating wind that dominate wind directions, climate, and weather. Drag the
following terms to these locations on the globe.
, This figure shows the overall directions of atmospheric circulation. Drag the description for
each region to its correct position on the map.
(11-10)
Which of the two globes showing cloud cover is most likely to represent conditions during the
Northern Hemisphere summer?
the left globe
Which of the two globes showing atmospheric pressure is most likely to represent conditions
during the Northern Hemisphere summer? Higher pressure is lighter on these globes.
(11-12) the right globe, because the subtropical high pressure in the Atlantic is shifted
northward
This globe from the atmospheric moisture investigation shows specific humidity, with blue
and green being highest. Which part of Africa has the highest specific humidity?
along the equator
This globe from the atmospheric moisture investigation shows precipitation, with higher
amounts in green and blue. Which of the following is a general pattern of precipitation across
Africa?
(11-14) It is highest close to the equator, and lower to the north and to the south
This globe from the atmospheric moisture investigation shows land cover, with green being
vegetation and tan and brown being bare rock and sand. The largest green areas on the land-
cover globe (they are dark on a black and white version) correlate most clearly with which
aspect?
(11-15) high amounts of precipitation
This globe from the atmospheric moisture investigation shows land cover, with green being
vegetation and tan and brown being bare rock and sand. The areas with the least vegetation
(they are light on a black and white version) correlate most clearly with which aspect?
(11-15) low specific humidity, water vapor, and precipitation
This globe from the atmospheric moisture investigation shows land cover, with green being
vegetation and tan and brown being bare rock and sand. What feature correlates with the
area with almost no vegetation in northern Africa?
(11-15) the Sahara
