The dry adiabatic rate is the rate at which - Correct Answers -temperature changes in a
rising or descending parcel of unsaturated air
During the ice crystal process of rain formation - Correct Answers -ice crystals grow
larger at the expense of the surrounding liquid cloud droplets.
The Earth's atmosphere is ordinarily - Correct Answers -conditionally unstable
The collision-coalescence process for precipitation formation usually takes place in -
Correct Answers -warm clouds

Answers -cumulonimbus
Ice nuclei may be: - Correct Answers -certain clay materials, bacteria in decaying plant
leaf material, and/or ice crystals
The temperature of a rising moist air parcel decreases with increasing height slower
than that of a rising dry air parcel is due to - Correct Answers -latent heat released
during condensation.
The vertical motion of air is called _____ by meteorologists. - Correct Answers -
convection.
, Which of the following combinations would normally occur and allow cloud formation? -
Correct Answers -air rises, expands, and cools
The rate at which the actual air temperature changes with increasing height above the
surface is referred to as the - Correct Answers -environmental lapse rate.
If a saturated air parcel is lifted from 1 km height to 2 km height, an average, its
temperature will drop ___. - Correct Answers -6°C.
The most common ice crystal shape is - Correct Answers -dendrite
If the environmental lapse rate is less than the moist adiabatic rate, the atmosphere is -
Correct Answers -absolutely stable
Which cloud water drops fall faster in the air? - Correct Answers -Large
The difference between the "moist" and "dry" adiabatic rates is due to the fact that -
Correct Answers -latent heat is released by a rising parcel of saturated air.
A conditionally unstable atmosphere is with respect to unsaturated air and with respect
to saturated air. - Correct Answers -stable, unstable
If an air parcel is given a small push upward and it continues to move upward on its own
accord, the atmosphere is said to be - Correct Answers -unstable
_____ clouds would most likely form in an very unstable atmosphere? - Correct
Answers -cumulonimbus
The rate at which the temperature changes inside a rising (or descending) parcel of
saturated air is called - Correct Answers -the moist adiabatic lapse rate.
If you observe large raindrops hitting the ground, you could probably say that the cloud
overhead was and had updrafts. - Correct Answers -thick, strong
What is most likely to happen if air rises, expands, and then cools? - Correct Answers -
cloud formation
What types of precipitation are we expecting at ground surface from a temperature
profile with a shallow freezing layer? - Correct Answers -Freezing rain
Which of the following is NOT a way of producing clouds? - Correct Answers -air
motions caused by subsidence

is 24 °C, then the air temperature at 2 km above the ground is about _____. - Correct
Answers -8 °C
