EAPS 106 FINAL EXAM QUESTIONS
AND ANSWERS
What happens to warm, moist air when it rises? - Correct Answers -it expands, cools,
and condenses into water droplets
What happens when a cold air mass collides with a warm air mass? - Correct Answers -
It forces the warm air up rapidly and produces thunderstorms
Which is heavier dry air or moist air? - Correct Answers -Dry air
What causes lightening? - Correct Answers -separation of electrons/charges (base- and
top+)
What is the difference between a tropical depression, a tropical storm, and a cyclone? -
Correct Answers -wind speed:
tropical depression <39 mph
tropical storm 39-74 mph
cyclone: >74 mph
What provides the energy for hurricanes and what happens when they venture over
land? - Correct Answers -Water vapor from warm tropical waters fuels hurricanes, so
when they hit land there isn't enough energy and they fizzle out
When is the primary north Atlantic hurricane season? - Correct Answers -August-
October
What causes thunder? - Correct Answers -lightening heats up air, causing a rapid
expansion
What causes hail? - Correct Answers -Thunderstorms. When strong winds push
raindrops up into the atmosphere and cold air freezes them
What distinguishes supercell from all other thunderstorms and how do supercell
develop? - Correct Answers -Supercell are large thunderstorms that rotate and form
strong wind shears that lead to horizontal vortex that is then rotated upwards
Why is hail often found in front of a tornado? - Correct Answers -Downdraft will lead the
updraft, so the updraft is right behind the downdraft (where the hail is)
Which way does the wind blow near a tornado? - Correct Answers -towards the tornado
, Tornados occur worldwide, how many tornados occur in the US each year? - Correct
Answers -1,000 per year
How the Enhanced Fujita Scale rates tornados? - Correct Answers -based on damage
When is the prime season for tornados? - Correct Answers -during the spring
That Doppler radar cannot easily measure what - Correct Answers -tornado wind
speeds
Where do you take shelter from a tornado while outdoors? - Correct Answers -indoors
Where do you take shelter from a tornado while indoors? - Correct Answers -in the
basement or a place with little to no windows
Where do you take shelter from a tornado while in a car? - Correct Answers -drive away
at right angles or in a low spot
What is the biggest danger from tornados? - Correct Answers -flying objects
What can tornados generally pick up? - Correct Answers -cars, shudders, barn walls,
small or big animals, trucks
Can tornados be generated by wildfires? - Correct Answers -yes, they are called fire
whirls
How long fighting lines put out by long-line sword fishing boats can reach? - Correct
Answers -40 miles, with over 1,000 hooks. Overfishes, too much supply (bad for the
market)
What is the difference between a hurricane, and cyclone, and a typhoon? - Correct
Answers -A hurricane is a tropical cyclone, an organization of a large number of
thunderstorms. A cyclone is the generic name for all of them. The only difference is
location. Cyclones = South Pacific. Typhoon= Northwest Pacific. Hurricanes = the
Atlantic and Eastern Pacific
Why cyclones cannot form on the equator? - Correct Answers -Without rotation induced
by the coriolis effect, groups of thunderstorms cannot organize themselves into a
cyclone. The coriolis effect disappears on/along the equator
What are the wind and pressure conditions found in the eye and the eye wall? - Correct
Answers -The eye has the lowest pressure and lowest winds, and the eye wall has the
highest winds
What is the Saffir-Simpson intensity Scale based on? - Correct Answers -wind speeds
