If you are heating water in a pan on the stove, the water at the bottom of the pan will warm first. Since warm water is lighter, it will rise, and cool water from the top will flow down to replace it. This is called convection, and will continue until all the water is hot.
Convection currents can occur in large bodies of water, in the atmosphere, or beneath the earth's crust. All that is needed is a warmer, lighter fluid below a cooler, heavier one.
Convection currents which make the Earth's crust float on the mantle are caused by the hot magma below. Convection currents can occur in all kind of hot mixes, even when you are making soup or pudding.
The hot material at the deep will rise (because it is hotter, like hot air goes up) by that rising it will start to cool and then sink again to the deep where it will heat up and start rising and so on in an everlasting cycle.
Convection currents are sent into motion by warm or hot air. This is because the hot air is able to quickly replace the cold air until it turns cold itself.
Heat transfer caused by fluids...
convection currents are set into motion by heat.without heat the convection currents would stop when all the material reaches the same temperature.
move in circular motion.
The continental plates are continually in motion due to the convection currents. The convection currents are driven from heat generated from radioactive decay within the earth.
Earth is like a giant magnet because of convection currents in the mantle. Convection is the transfer of hear by the motion of particles in a fluid.
currents caused by the motion of heated molecules

No. Convection currents are the circular motion of earth's wind. If the earth did not rotate, convection currents would not be. Does that make sense?
Convection is transferred by the larger-scale motion of currents in the fluid.
The three factors that set convection currents in motion are: the heating and cooling of fluid, change in its density, and the force of gravity combine to set it in motion.
Not conduction, but convection currents, are what drive winds and many ocean currents.
The three main factors that are responsible for setting convection currents in motion are the cooling and heating of fluid, any changes to their density and the force of gravity. These factors combine to set the currents in motion.
