Convection

Did you know that convection happens when heat is transferred through a fluid? If fluids like air and water are warmed up then the molecules inside them will move very fast. After that the molecules will bump into each other frequently. Then the molecules will spread out and make the fluid have more volume. You cannot see convection happening. But if you boil a pot of water and watch it carefully then you can see convection happening. Convection controls the movement of air and tectonic plates. The circulation of the air around us is convection. Warm material inside earth's mantle rises and falls. It endlessly does this in a cycle called convection cells. In conclusion now you know that convection is almost everywhere.
