Question

1.)Why does a parcel of air expand as it rises up in the atmosphere?

a.)It is under less pressure as it rises.

b.)It is under more pressure as it rises.

c.)Its temperature cools as it rises.

d.)Its temperature warms as it rises.

2.)What does a completely unsaturated atmosphere look like visually if you look up in the sky?

a.)Clear sky

b.)Cumulonimbus will be visible.

c.)Stratus will be visible.

d.)A halo will be visible around the sun or moon.

3.)What does "Absolute Stability" represent?

a.)A parcel of air that is warmer than the surrounding air at all elevations.

b.)A parcel of air that is cooler than the surrounding air at all elevations.

c.)A parcel of air that is warmer than the surrounding air below the LCL, then cooler than the surrounding air above the LCL.

d.)A parcel of air that is cooler than the surrounding air below the LCL, then warmer than the surrounding air above the LCL.

4.)During the Bergeron (Ice-crystal process) of precipitation:

a.)Only ice crystals need to be present in the cloud.

b.)Ice crystals grow larger at the expense of the surrounding super-cooled liquid cloud droplets.

c.)The cloud must be a cumulonimbus cloud.

d.)The temperature in the cloud must be -100 degrees Celsius or below.

Answer 1

1) option a) is correct.

2) option a) is correct

3) option b) is correct

4) option b) is correct

Step-by-step explanation:

1) option a) is correct.

as the air rises the pressure decreases.

2) option a) is correct

in completely unsaturated atmosphere sky looks clear.

3) option b) is correct

when a parcel of air that is cooler than the surrounding air at all elevations then is the condition of absolute stability.

4) option b) is correct

During the Bergeron (Ice-crystal process) of precipitation, at the expense of surrounding super cooled liquid ice crystal grow large.
