AIG Cloud Formation

What is a cloud primarily composed of?

• A mass of water vapor

• A mass of condensed water droplets

• A mass of ice crystals

• A mass of atmospheric gases

Which of the following is a key condition for cloud formation?

• Decreasing altitude and increasing temperature

• Stable atmospheric conditions and low humidity

• Lifting air and decreasing temperature with altitude

• High atmospheric pressure and absence of water vapor

What happens to water vapor at the Lifting Condensation Level (LCL) and Dew Point (DP)?

• It evaporates into a gaseous state.

• It freezes into ice crystals.

• It changes phase from vapor to liquid water.

• It becomes less dense and rises further.

What is the primary role of Cloud Condensation Nuclei (CCN) in cloud formation?

• To absorb solar radiation and heat the atmosphere.

• To act as a catalyst for water vapor to condense into liquid water.

• To increase the atmospheric pressure at high altitudes.

• To prevent the formation of water droplets.
