Concept:Rainfall requires moist air to rise, cool, and condense; descending air prevents this process.
Explanation:Converging wind forces air together and pushes it upward.
This upward motion cools the air and encourages condensation and rainfall.
Ascending wind lifts air to cooler heights, causing condensation and rainfall.
Warm wind holds more moisture and can produce rainfall if it rises.
Descending wind makes air sink, compress, and become warmer.
This warming prevents condensation, so descending wind does not encourage rainfall.
Answer:Descending wind does not encourage the formation of rainfall.
