During a change in state, energy is transferred in the form of
motion
heat
moisture
light
When a liquid absorbs energy and changes to a gas, what takes pace?
condensation
sublimination
deposition
evaporation
The formation of frost on a cold windowpane is an example of which of the following?
sublimination
condensation
deposition
transpiration
What does relative humidity indicate?
how close air is to saturation
the amount of heating needed for evaporation
the amount of water vapor in the air
the ratio of water vapor to CO2 in the air
When the temperature of air rises, the amount of water needed for saturation
increases
decreases
stays the same
Relative humidity of a sealed flask of air can be changed by changing the air's temperature or by
shining light on the flask
adding or removing water vapor
bringing the flask to a different latitude
adding or removing particles of soil
When air expands, it
cools down
has more water vapor
warms up
becomes heavier
Which process produces rising air due to unequal heating of the Earth's surface?
frontal wedging
convergence
orographic lifting
localized convective lifting
When is air most likely to rise?
when it is unstable
when it is cooling
when it is dry
when it is stable
Which of the following is NOT needed in air for water condensation to occur?
temperature at the dew point

What does Bergeron process explain?
formation of clouds
movement of air masses at fronts
