the form of energy would be heat. convection currents are caused by uneven heating of air or fluid. The warmer fluid is more boyant than the cooler fluid, so it floats to the top, and creates a "convection current"
Convection currents form when a fluid is heated from the bottom, causing it to rise and create a circulating flow. If a fluid is heated from the top, there is no temperature difference to drive the circulation, preventing convection currents from forming. Heat needs to be applied at the bottom to induce the necessary buoyancy-driven flow for convection currents to occur.
Convection currents move in the Mantle.
