Example:
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.

Convection Current: The movement pattern in a fluid caused by temperature differences within the fluid. Convection current. In simple terms, a convection current is when warmer fluid rises and cooler fluid sinks, creating a circular flow.
