Atmospheric Physics and Humidity Questions

Multiple choice

Transpiration would be lowest when

  1. wind velocity is high

  2. enough water is present in the soil

  3. atmospheric RH is high

  4. temperature is high
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

High relative humidity reduces the water vapor gradient between leaf and atmosphere, decreasing transpiration. High wind velocity increases transpiration by removing the boundary layer. High temperature and adequate soil water both increase transpiration.

Multiple choice

A storm is predicted if the atmospheric pressure

  1. rises suddenly

  2. rises gradually

  3. falls suddenly

  4. falls gradually
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A sudden drop in atmospheric pressure is a classic indicator of an approaching storm or cyclonic weather system.
