What is connvection currents?

Convection currents are the continuous movement of fluid caused by differences in temperature and density within that fluid. When a fluid is heated, it becomes less dense and rises, while cooler, denser fluid sinks, creating a circular motion. This process is essential in various natural phenomena, such as the movement of tectonic plates in the Earth’s mantle and atmospheric circulation. Convection currents also play a crucial role in heat transfer in liquids and gases.
