A temperature difference leads to an energy transfer from an area of higher energy to one of lower energy Convection currents are circular motions of fluid, such as air or water, driven by temperature differences Convection that occurs naturally is called natural convection or free convection.

Atmospheric convection currents can be set up by local heating effects such as solar radiation (heating and rising) or contact with cold surface masses (cooling and sinking).
As the warm fluid rises, it displaces cooler fluid, which is more dense and sinks to take its place
This creates a continuous cycle, known as a convection current, that transfers heat over time. Convection currents are movements within a fluid, caused by the tendency of warmer, less dense material to rise and cooler, denser material to sink These currents are a fundamental mechanism driving heat transfer in the earth's interior, impacting geological processes such as plate tectonics and volcanic activity. The meaning of convection current is a stream of fluid propelled by thermal convection.
Convection currents are the circular movements of fluid, such as air or liquid, caused by the heating and cooling process, which results in the transfer of heat energy. Convection currents are a fundamental physical process in fluid dynamics that involve the movement of fluid (liquid or gas) caused by variations in temperature within the fluid. This hot water rises to the top, while cooler water sinks to the bottom to get heated This circular movement is a convection current
Convection currents are responsible for ocean currents, weather patterns, and even the movement of earth's tectonic plates!
