Earth’s interior is actually composed of three solid layers and a single outer liquid layer which is pure molten metal, believed to be nearly as hot as the surface of the sun (and to my friends at the Shavertron Discussion group, this doesn’t include the portions that are inhabited by evil Deros, of course). The innermost layer is a large, iron ball infused with sulfur and other minerals which, though surrounded by intense heat, is also compressed from every angle by such pressure that it remains solid. Liquid iron makes up the outer core, and movement of these liquid outer regions works to create an electrical current, and this in turn generates the magnetic field surrounding our planet, which is close to 1,500 miles thick.
However, such magnetic changes are nothing new, and if anything, in contrast to the short time humans have spent on Earth, such fluctuations might be considered commonplace. In the distant past, Earth’s magnetic field has actually reversed hundreds of times, though such a change might take up to thousands of years to take place in a single instance. So far as how strange phenomenon might relate, could it be that areas where such magnetic phenomena are more active are also host to more paranormal activity?(above taken from the Gralien Report website )
