What's your big idea?
The core is moving outward.
The axis of the core forms the earth’s magnetic poles. We have tracked the migration of the axis of the core, by observing the movement of the magnetic poles in comparison to the earth axis of rotation. From this, we can see that the core is moving. Observations show that the core is migrating, off from center, outwards toward Indonesia and the pacific basin. As the core moves closer to the mantel, its rotating force generates the heat that melts the mantel into churning hot magna, which in turn is pumped around by the giant dynamo. The crust is thinnest in the region where the core is off centered; this is the reason why there are so many active volcanoes in the areas around the pacific basin.
