Question

Quizplus · Accepted Answer

Convection refers to the process of heat transfer through vertical movements of a fluid, such as air. As the air near the surface of the Earth is heated it rises and cooler air flows in to replace it, creating a cycle of vertical movement. This is why convection is often associated with thunderstorms, as the upward movement of warm, moist air can lead to the development of cumulonimbus clouds and lightning.
