What is the general pattern of magma circulation in the mantle?

Mantle convection is the very slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface. ... Accretion occurs as mantle is added to the growing edges of a plate, associated with seafloor spreading
