Best Answer

Temperature differences in the mantle drive convection currents because warm material is less dense and rises, while cooler material is more dense and sinks. This movement creates a circular flow as the cooler material sinks and gets heated, while the warmer material rises and cools down. The density variations caused by the temperature differences are a key driver of convection in the mantle.
