The process involving the transfer of energy in the form of heat through a fluid is known as convection. In convection, warmer, less dense fluid rises while cooler, denser fluid sinks, creating circulation patterns. This mechanism is essential in fluids such as air and water, affecting weather patterns, ocean currents, and heat distribution in various environments. Convection plays a significant role in heat transfer within the atmosphere, contributing to climate dynamics and influencing temperature variations across different regions.
