The "mantle plume" thus formed, once established, continues to channel hotmaterial from the mantle base until the reservoir is emptied.

The mantle's motions, analogous to those in a pot of boiling water, cool the mantle by carrying hotmaterial to the surface and returning cooler material to the depths.
