The evidence of volcanic rock layers with opposite magnetic fields to Earth's aligns with the hypothesis of geomagnetic reversal. This suggests that Earth's magnetic field has flipped polarity multiple times throughout its history.

In the Dynamo Theory, the magnetic field of the earth is created in the outer core. The fluid contained in the outer core creates and maintains the magnetic field during rotation.
When lava cools and solidifies, magnetic minerals within it align themselves with Earth's magnetic field. By studying the orientation of these minerals in lava layers, scientists can track changes in the Earth's magnetic field over time. Reversals of the Earth's magnetic field are reflected in lava layers as bands of alternating magnetic orientation.

The two layers of earth that are made up of liquids are the crust and the outer core. The crust is the surface of the earth which is where the oceans are. The outer core is made up of iron and is the creator of the earths magnetic field.

The layers of the earth are larger than out atmoshpere.
They form by the cooling of ferrous rock at the time it transitions from a molten state to a solid state. The ferrous particles are trapped in the orientation of the earths current magnetic field. The earths magnetic field alternates every certain number of years (a huge number like 500,000 years.) Since rock will cool at different times alternating layers of rock can have a completely opposite magnetic orientation. They are useful because you can tell the relative age of the different layers of rock based on this evidence. Hope this helps. Very brief and crude explanation.
