    The core is moving outward.

    Most everyone at some point in his or her life will ponder the notion that the earth core is a giant solid metal ball in the center of the earth. Few will ever explore the actual physics of its electromagnetic field and all the affects it plays on the life of this planet. We do know that several individual layers of differentiation lay between our feet and the giant rotating solid metal dynamo we call the core. Each of these layers are made up of a variety of minerals that react differently to the spinning magnetic field. Some of these reactions make up the forces that, generates the earth’s magnetosphere and ozone layer, both of which are key to sustaining an atmosphere and life.
    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.
