The temperature of the particles is one of the factors that caused the formation of current. When substance such as water is heated, the less dense particles shall rise while the denser ones will sink. However, when the hot less dense particles will cool, the other less dense particles will rise, this phenomenon is called the convection current. The plates are being
dragged by the convection currents as they moved slowly thus, tectonic plates
are able to move slowly along the tectonic boundaries,pushing each other,
sliding past each other and drifting away from each other
