What is a convection current?
1 answer
A convection current is a process in which heat is transferred through a fluid (such as air or water) from a warmer area to a cooler area. This transfer of heat creates a circular motion of the fluid as the warmer, less dense fluid rises and the cooler, denser fluid sinks. Convection currents play a key role in the movement of air in the atmosphere and water in the oceans, helping to distribute heat and maintain a balanced temperature in these systems.
