GEOG 1900 Final Study Guide – Complete With
Solutions
Ocean Convergence Correct Ans - Wind pushing up against a water mass
and causing downwellinf
Ocean divergence Correct Ans - Wind pushing away from water mass
causing upwelling
ESNO Correct Ans - El Niño Southern Oscillation, see-sawing of air
pressure over the S. Pacific irregularly every 3-7 years
El Niño _______the mean state while La Niña _________it Correct Ans -
Reverses, intensifies
El Niño impacts Correct Ans - Less rich and productive ocean, wetter
and colder winter in US, changes ITCZ location
Air mass Correct Ans - A huge body of air that has similar temperature,
humidity, and air pressure at any given height
source region Correct Ans - the area over which the air mass forms
Two classifications of air masses Correct Ans - By latitude and by nature
of source region (temp and moisture)
air mass temperature classifications Correct Ans - Arctic, Polar, Tropical
air mass moisture classifications Correct Ans - Continental, maritime
Front Correct Ans - The boundary where unlike air masses meet but do
not mix
Types of fronts Correct Ans - cold, warm, stationary, occluded
Warm front Correct Ans - the front of an advancing mass of warmer air
Typically slower and less steep and intense
, Cold front Correct Ans - A front where cold air moves in under a warm
air mass.
Typically faster, steeper, more intense
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
Dryline Correct Ans - A boundary that separates warm, dry air from
warm, moist air. It usually represents a zone of instability along which
thunderstorms form.
mid-latitude cyclone Correct Ans - A cyclone that forms in the middle
latitudes at the polar front.
Low pressure center
Convergence _________ cyclones, divergence________ Correct Ans -
Weakens, strengthens
The wavier the jet stream.... Correct Ans - The stronger the cyclone
Occluded fronts are typically formed by... Correct Ans - Cyclones
storm tracks Correct Ans - seasonally shifting paths followed by
migrating low pressure systems
lightning Correct Ans - A sudden spark, or energy discharge, caused
when electrical charges jump between parts of a cloud, between nearby
clouds, or between a cloud and the ground.
How lightning forms Correct Ans - Positive charges on the ground get
attracted to the negative charges at the bottom of the cloud
*Their collision creates lightening
Ice and grauple collision
stepped leader Correct Ans - The channel of partially charged air; the
breakdown in charges in between positive and negative regions
