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.

How is the earth's magnetic field created?
A few % of the magnetic field comes from the stream of charged particles coming from the Sun. This is why the magnetic field varies greatly in Polar Regions during a sunspot storm.The majority of the field is generated deep inside the Earth by electrical currents in the liquid part of the outer core. The nett result of these currents generates a magnetic field.The Curie Temperature of magnetic materials ensures that there are no magnetic materials deep in the Earth.
What is the space created when the dural layers separates?
The space created when the dural layers separate is called a dural venous sinus. These sinuses are responsible for draining blood and cerebrospinal fluid from the brain and are located between the layers of the dura mater.
How are suns magnetic fields produced?
The magnetic fields of suns are believed to be generated by the motion of charged particles (primarily ionized hydrogen) within the star's outer layers. As these charged particles move and circulate, they create electric currents, which in turn give rise to magnetic fields. The complex interactions between these moving charged particles and the magnetic fields help to sustain the sun's magnetic activity.
What two forces cause the sun's magnetic field to become stronger and tangled?
The two forces that cause the sun's magnetic field to become stronger and tangled are the differential rotation of the sun's layers, which creates a twisting effect on the magnetic field lines, and the convective motion of plasma within the sun, which amplifies and distorts the magnetic field. These processes can lead to the formation of sunspots, solar flares, and other solar activities.
Why does magnetic striping happen?
The plate tectonics based theory ha a three pronged aproach; both the zebra-like magnetic striping and the construction of the mid-ocean ridge system, the seafloor spreading hypothesis (SFS) quickly gained converts and represented another major advance in the development of the plate-tectonics theory. Furthermore, the oceanic crust now came to be appreciated as a natural "tape recording" of the history of the geomagnetic field reversals (GMFR) of the Earth's magnetic field. Nowadays, extensive studies are dedicated to the calibration of the normal-reversal patterns in the oceanic crust on one hand and known timescales derived from the dating of basalt layers in sedimentary sequences (magnetostratigraphy) on the other, to arrive at estimates of past spreading rates and plate reconstructions.
How does the magnetic orientation of lava layers demonstrate reversals of earths magnetic field?
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.

Volcanic rock shows that some layers have magnetic fields that are aligned opposite to Earths This evidence BEST fits which hypothesis?
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.
Which two layers of the earth are liquid?
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.

How do magnetic stripes form on the ocean floor and how are they significant?
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.
