Default Why does fermenting beer move?

Not sure if this has been discussed before but I have always wondered, especially have brewed quite a few Highly vigorous IPAs and recently a big scotch heavy ale. If anyone has links to the science behind why yeast moves around in the wort while fermenting, or if they know why I love to learn more! Thanks

I'm no expert but I would thing it due to releasing co2 and the temperature fluctuations in the wort.

1) Gas rises. Yeast expel CO2. It rises through the liquid and all sorts of particle catch a ride.

2) Convection. They yeast are producing heat and warming the surrounding wort. Heat rises, so you get currents going upward. The warm wort gets exposed to cooler air, starts to cool, and then sinks.

cool, thanks. I thought it had to do with the temp of the yeast as it ferments but I didn't realize it makes it move that much. I am amused by simple things and I love to watch it floculate and ferment.
