Convection current is current which is caused due to the movement of group of molecules and also called difference in pressure and heat in earth
The convection current circulates in mantle when the earth spins whereas when the earth rotate it causes pull of matter in the mantle of earth.
As a result the earth rotation respond to mantle convection current where it travels.
