Convection Currents

  1. Sep 24, 2004 #1
    Do convection currents occur in all bodys of water and gas?
    Or are they only at a certain temperature, under certain circumstances?

    I believe that on a very small level, they occur under all circumstances in all fluids. In theory, any variation in, for example, the exterior temperature around a Thermos bottle will cause the fluid inside to exhibit convection. More practically, however, convection occurs most notably when specific sources of heat/cooling exist, for example in a room with a heater. Remember how convection works and you should be able to figure out when it will occur.
