The convection currents

WebConvection is also seen in the rising plume of hot air from fire, plate tectonics, oceanic currents (thermohaline circulation) and sea-wind formation (where upward convection is also modified by Coriolis forces). In engineering applications, convection is commonly visualized in the formation of microstructures during the cooling of molten ... WebApr 23, 2024 · Convection currents rely on the constant cyclical motion of air, water and other substances to distribute heat. As heated air rises, for example, it pulls cooler air into its place -- where it can be heated, rise, and pull in more cool air.
