a heat energy traveling upward from the hot lower mantle to the cooler upper mantle
tend to move a fluid or gas particles from one place to another
Convection currents work like a lava lamp, the heat source is at the bottom of the lamp (like the inner core). The hot material floats to the top. When the material gets to the top it cools down. This forces it to sink back to the bottom because of the loss of heat. It is heated again and it's a long cycle that never stops.
hope this helps a little :D
