QUESTIONS WITH ANSWERS.
Is latent heat of evaporation absorbed or released? Does this
make latent heat of evaporation a cooling process or a warming
process? (think of sweat evaporating) - correct answer --
evaporation heat is ABSORBED so it's a COOLING process
- vapor contains potential energy, there's heat "hidden away" in
water vapor
Is latent heat of condensation absorbed or released? Does this
make latent heat of condensation a cooling process or a warming
process? (think of water droplets on cold water bottle) - correct
answer -- condensation heat is RELEASED within rising air
parcels so it is a WARMING process.
- vapor goes back into a liquid state and releases heat
Cooling processes/heat absorbed - correct answer -evaporation,
melting, sublimation
, Page | 2
Warming processes/heat released - correct answer -freezing,
deposition, condensation
Melting - correct answer -ice to liquid
Evaporation - correct answer -liquid to vapor
Sublimation - correct answer -ice to vapor (ex: dry ice)
Condensation - correct answer -vapor to liquid
Deposition - correct answer -vapor to ice (ex: snowflakes and
frost)
Freezing - correct answer -liquid to ice

Troph = _____ - correct answer -line (troph of low pressure = line
of low pressure)
THE EARTH AND THE SUN
How much of the Suns energy is intercepted by Earth? - correct
answer -2 billionths of the Suns Energy
THE EARTH AND THE SUN
Solar energy represents _____% of energy that heats the earth's
surface - correct answer -99.9%
THE EARTH AND THE SUN
What would happen to global scale winds if the sun stopped
shining? - correct answer -they would slowly cease
THE EARTH AND THE SUN
What causes day and night? - correct answer -the earths rotation

What causes seasons? - correct answer -the revolution of the
earth
You look at an upper air station model and note that the circle at
the center of the station model is filled/colored in... This tells you
that - correct answer -the dew point depression is 5 degrees or
less
On the vernal Equinox, here in the northern hemisphere the sun is
most overhead of... - correct answer -the Equator
Which surfaces has the most variable albedo Values based on
other factors (color, moisture content, slope angle, textures, etc) -
correct answer -water/ Ocean areas
The lines drawn to connect equal dew point temp. As plotted on
weather charts, are properly referred to as_____. - correct answer
-isodrosotherm
I ask you to view on upper air/constant height chart and to review
the conditions at that height as represented by a station model in
