Convection Current
Convection current explained in an easy to understand way:
Imagine you're in a crowded elevator and everyone is trying to reach different floors. Just like people in an elevator move up and down to reach their desired levels, warm and cool parts of a fluid move in a similar pattern. As the fluid heats up, it rises, similar to people trying to get to higher floors, while cooler fluid sinks, akin to people heading to lower floors. This movement creates a continuous cycle, like an elevator's constant up and down motion, illustrating the convection currents caused by temperature differences within the fluid.
Practice Version
Convection Current: The movement pattern in a fluid caused by temperature differences within the fluid. Convection current. It's the circular motion of fluid, like water or air, caused by warmer, less dense areas rising and cooler, denser areas sinking.
