Ultimately,the buoyancy of a rising air parcel is dependent upon its:
A)composition.
B)volume.
C)concentration of water vapor.
D)rate of cooling relative to the surrounding air.

Question

Quizplus · Accepted Answer

The rate of cooling relative to the surrounding air determines the buoyancy of a rising air parcel. As the air parcel rises, it cools due to expansion and loses heat to the environment at a rate dependent on the temperature and humidity of the surrounding air. If the parcel cools at a rate slower than the surrounding air, it remains warmer and less dense, leading to buoyancy and upward movement. If the parcel cools at a rate faster than the surrounding air, it becomes cooler and denser, leading to sinking. Factors such as composition and concentration of water vapor can influence the rate of cooling, but ultimately it is the rate of cooling relative to the surrounding air that determines the buoyancy.
