differences in temperature and salinity.
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.

when a substance is cooler at the surface, the density increases in the substance.
Density Current
The density of a material depends on the mass and the volume of that material. In order to find the density of a material you must multiple the mass of the material and the volume of the material.
