CSCC GEOG1900 EXAM 2 – Questions With SolutionsWhat are the features of surface air? Correct Ans - It moves from high to
low pressure.
It is deflected to the right in the northern hemisphere by the Coriolis force. It
is deflected to the left in the southern hemisphere by the Coriolis force.
At the shore, during a normal 24 hour period, a land breeze is most likely to
occur Correct Ans - in late afternoon (4pm)
Geostrophic winds are subject to Correct Ans - the Coriolis effect
As evidenced in Lab 7, an eye dropper (a Cartesian diver) lifts upward through
the water in a plastic bottle, like air in the atmosphere, when: Correct Ans
- releasing pressure, and reducing dropper density
Cyclones Correct Ans - winds around centers of low atmospheric
pressure
anticyclone Correct Ans - An atmospheric condition of high central
pressure, with currents flowing outward.
Thermoclines Correct Ans - narrow layers of fast temperature change
that separate a warm upper layer of water and cold deeper waters
In the Hadley cell, air rises from ________________ and descends into
____________________. Correct Ans - ITCZ............subtropical high pressure
cells.
prevailing winds Correct Ans - Global winds that blow constantly from
the same direction
Westerlies Correct Ans - Dominant winds of the mid-latitudes. These
winds move from the subtropical highs to the subpolar lows from west to east.
ITCZ (intertropical convergence zone) Correct Ans - A region of low
pressure near the equator where air masses meet. Also known as the
doldrums.
, WInd circles clockwise around the Correct Ans - North Atlantic's Azores
High
The eastern half of the US is relatively moist and rainy because of Correct
Ans - the positioning of the North Atlantic's subtropical high pressure belt
and the Atlantic's subtropical western boundary current.
The west coast is arid due to Correct Ans - cool eastern boundary
currents
cT air mass Correct Ans - continental tropical air mass with warm, dry,
unstable air
cP air mass Correct Ans - continental polar air mass with cold, dry,
stable air
mE air mass Correct Ans - maritime Equtorial
Mid-lattitude cyclones Correct Ans - surface low pressure of
atmospheric instability and high precipitation probability
an Air front Correct Ans - a boundary separating air masses.A wind shift
line.
warm front Correct Ans - a front where warm air moves over cold air
and brings drizzly rain and then are followed by warm and clear weather
cold front Correct Ans - A front where cold air moves in under a warm
air mass.
occluded front Correct Ans - a front where a warm air mass is caught
between two colder air masses and brings cool temperatures and large
amounts of rain and snow
stationary front Correct Ans - A boundary between air masses that don't
move possibly causing rain for several days
yellow line represents Correct Ans - dew point
