the possible source of the earths magnetism is the earths what?

Answer 1

The core of earth is made up of solid iron and nickel. The outer core is mostly semi-liquid iron. The currents of the outer core moving around the solid inner core create a magnetic field. This is where earths magnetism comes from.

Answer 2

most believe it has to do with the metalic core and friction of movement, if the core slowed down or cooled, the magnetic field would die, as it greatly has on mars, and then life would fade away.

Recently, a new theory is coming into play that heavy atomic elements may be reacting in the core, providing the fields, but it's unknown how long they will last if that is the case.

Answer 3

The nickel and iron in the core of the earth

Answer 4

are we doing your homework for you?

i think its the molton iron core. This would explain why the magnetic north pole migrates.

Answer 5

The earth's core is molten iron.

Answer 6

The strong force and weak force of atoms, or rather the inherent ability of atoms to attract or repel one another.

Answer 7

Adam L is spot on. He is the only one who's answered thus far who knows what he's talking about.

Answer 8

This is a guess , the rotation of the Earth on it's axis.

Answer 9

All the refrigerater magnets.

Answer 10

hmm thats easy to answer..i forget the answer tho. lol im sure its on wikipedia.com. i think it has something to do with earths roation and gravity pull. not too sure.
