The property of matter that enables the formation of convection currents is a. "Fluids rise when they are less dense than the surrounding material." This phenomenon occurs because when a fluid (which can be a liquid or a gas) is heated, its particles move faster, spread apart, and the fluid's density decreases. Because it is less dense than the surrounding cooler fluid, it rises. As it rises, it displaces the cooler, denser fluid, causing the cooler fluid to sink. This movement creates a cycle or current called a convection current.
