How clouds are formed part II 2022

Front

What are the ingredients necessary for a cloud to be created?

Back

Dust, water vapor, cool temperature.

Front

What is the process called when water vapor changes to a liquid?

Back

Condensation.

Front

With which type of lapse rate does the air usually lose temperature fastest while it is rising?

Back

Dry Adiabatic Lapse Rate.

Front

As warm, dry air mass rises, it cools down by how many degrees Celsius every 1000 meters increase in altitude?

Back

10 degrees Celsius.

Front

What type of atmospheric stability is shown when the air is rising and cooling?

Back

Unstable.

Front

What is evaporation?

Back

The process where liquid water turns into water vapor.

Front

Define relative humidity.

Back

The amount of water vapor present in the air compared to the maximum amount the air can hold at that temperature.

Front

What is the role of dust in cloud formation?

Back

Dust acts as condensation nuclei, providing surfaces for water vapor to condense upon.

Front

Explain the term 'lapse rate'.

Back

Lapse rate is the rate at which temperature decreases with an increase in altitude.

Front

What happens to air pressure as altitude increases?

Back

Air pressure decreases as altitude increases.
