    Convection is one form of energy transfer where heat energy is transferred by large scale movement in a gas or liquid. Convection currents form, which are streams of gas or liquid powered by convection. Some of this movement is caused by differences in density. You might remember that density how much matter there is in a given amount of space.

  • How is conduction and convection related to the weather .

    Aug 18, 2006 · Convection and conduction are both processes by which energy is moved around. Convection is the transfer of heat by currents within a fluid. This happens on the basic premise that warm air rises because it is less dense than its environment and cool air sinks because it is more dense than its environment (2).
