It takes about the one million years for
the magma to complete one circular
convection flow.


Sagot :

Answer:

False, since it takes more than one million years

Explanation:

Speeds can be faster for small-scale convection occurring in low-viscosity regions beneath the lithosphere, and slower in the lowermost mantle where viscosities are larger. A single shallow convection cycle takes on the order of 50 million years, though deeper convection can be closer to 200 million years.
