ATSC 113 FINAL: SNOW- SPORTS EXAM
QUESTIONS AND ANSWERS
Why are all snowflakes unique? - Answer-B/c as a snowflake falls, it goes through
regions of varying temperature and humidity which affects how it forms.
Why do skiiers/snowboarders apply wax to the bottom of their skis/ snowboard? -
Answer-To increase speedW
What does "C, cntrd" stand for? - Answer-Contour lines represent temperatures in
degrees Celsius
What does "MSLP" stand for? - Answer-Mean Sea-Level Pressure
Define corduroy - Answer-ridged effect on snow left by grooming machines that allows
for higher speeds b/c of uniform surface
Define fluid - Answer-Anything that flows easily
Waves transport...
(a) energy
(b) matter
(c) neither
(d) both - Answer-ENERGY!
Describe the wavelength and wave period of fast waves... - Answer-longer wavelength
shorter wave period
Describe the velocity and amplitude of Tsunamis in open ocean... - Answer-High
velocity
Small Amplitude
How does the angle at which a swell approaches the shore affect how the wave
breaks? - Answer-Waves that reach the shallow area of the shore first will break first
What is the Beaufort Wind Force Scale based on? - Answer-the amount of canvas sail a
full fledged frigate could carry
Which Beaufort Scale Values are best for recreational sailing and which are good for
advanced sailing? - Answer-Recreational Sailing=3-4
Advanced Sailing=5-6
, What is the difference b/w extra-tropical cyclone and tropical cyclones? - Answer-Extra-
tropical cyclone=cold core+fronts
Tropical cyclone= warm core+no fronts
Can you find stronger westerlies in the Northern Hemisphere or the Southern
Hemisphere? Winter or Summer? - Answer-Southern Hemisphere (b/c flow mostly over
water=> less frictional drag) during Winter!
Why do winds rotate around a high/low pressure region? - Answer-Coriolis Effect
What kind of force do winds exert on water surface that produces gyres? - Answer-Drag
force
Define storm surge - Answer-when a hurricane approaching land pushes a large
amount of water against the shore
Out of the following three, which can't be found at the equator?
(a)Hurricane
(b) Thunderstorm
(c)Heavy rain - Answer-Hurricane b/c no coriolis effect
What 3 things can turn away/stop a sea breeze? - Answer-1.mountains
2.opposite synoptic scale winds
3.coriolis force (turns it)
Why do land breezes generally form during nighttime but sea breezes form during
daytime? - Answer-Land breezes: at nighttime, clear skies, land+sea radiate heat--
>land radiates heat faster-->cools faster-->cool wind blows land-->sea
Sea breezes:at daytime,sun warm land+sea-->land easier to warm-->cool wind blows
from sea--> land
Where do katabatic wind go when...
(a)mountain slope=adjacent to coast line
(b)fjord
(c)valley floor w/ SOME slope - Answer-(a)flow offshore as land breeze
(b)cold air pooling
(c)mountain winds
How are inflows and outflows names? - Answer-They are named for the town that they
first pass over
Define convection - Answer-Upward movement of warm air
Define cloud diameter - Answer-height of cloud top above ground
