Lopsided Core ... of the Earth...

23 Apr 2010

At www.physorg.com/print191053615.html April 21st ... the inner core at the centre of the earth is growing as a result of crystalliation of iron in the liquid 'outer core' - so much so the 'solid core' permanently drifts eastwards. Why is the inner core asymmetrically out of shape? New light has been shed on this by research published in Science on April 16th. Variations in the core appear to match up directly with the shape of the earth's magnetic field.
