Answer:
a. True
Step-by-step explanation:
The dew point is the temperature at which air is saturated with water vapor and condensation occurs. When the temperature of the air reaches the dew point, moisture condenses into droplets, forming dew, fog, or cloud. The dew point is an important measure of atmospheric moisture and can have a significant impact on weather and climate. A high dew point indicates a high amount of moisture in the air, while a low dew point indicates low atmospheric moisture. The dew point is calculated based on the temperature and relative humidity of the air, and can be used to forecast the likelihood of precipitation or other weather-related events.
