Here's how it works:
* Heating: When a fluid (liquid or gas) is heated, the molecules in the warmer areas become less dense and rise.
* Cooling: As the warm fluid rises, it cools and becomes denser.
* Sinking: The cooler, denser fluid sinks back down, creating a circular motion.
Examples:
* Weather patterns: Large-scale convection cells in the atmosphere drive weather patterns like thunderstorms and hurricanes.
* Ocean currents: Convection currents in the ocean transfer heat around the globe.
* Boiling water: The bubbles that rise from the bottom of a pot of boiling water are a result of convection.
