Magnetic Field Reversals - an Explanation?
I came across THIS ARTICLE and found it very interesting. It connects subduction - all the way to the core - and magnetic field reversals. They reckon it takes 120m years for transportation from surface to core.
An increase in the amount of subduction leads to increase in magnetic reversals 120 million years later. I can hardly wait!
