Earth's magnetic field doesn't have much to do with tectonic plates. But both are caused by movement of the magma.

The magnetic field is caused by electrical currents flowing in the magma, roughly parallel with the Equator. [A few % of the field is caused by the flow of the Solar Wind past the Earth.]

Tectonic plates move around the surface of the Earth over the liquid magma. The gravity drag of the Moon causes the Earth's crust to rotate (very) slightly more slowly than the inner core.

Consider the shape of the island arc joining S America to the Antarctic. And the slow movement of the Pacific Ocean's floor with regard to a few (postulated) stationary hot spots. Such as Hawaii, and some ocean floor chains of sea-mounts East of New Zealand.

Why are magnet patterns important evidence for plate tectonics?

magnetic rocks on the ocean floor show that the Earths magnetic field has been frequently reversed forming new sea floor.


Where is Earths magnetic reversals recorded?

Earth's magnetic reversals are recorded in rocks that contain magnetized minerals, such as iron-bearing minerals like magnetite. When these minerals solidify and align with Earth's magnetic field, they preserve a record of the magnetic field at that time. Scientists can study these rocks to determine the timing and duration of past magnetic reversals.


What are plate tectonics and what does it have to do with the earths shape?

Plate tectonics are what each continent is on. They move and are continuing to move today. It has to do with the earth's shape because the plate tectonics move the continents around.


The patterns of iron particles found in sea floor rocks result from what?

The patterns of iron particles found in sea floor rocks result from changes in the Earth's magnetic field over time. As the molten rock solidifies into rock, the iron particles align with the Earth's magnetic field at that time, creating unique patterns that can be used to study the history of the Earth's magnetic field and plate tectonics.


What Is the theory that the earths lithosphere is divided into tectonic plates that move around on top of the asthenosphere?

A theory that says the lithosphere is divided into plates that move around on top of the asthenosphere is called '' plate tectonics''

Does plate tectonics produce earths magnetic field?

No. Earth's magnetic field is produced by currents in the liquid outer core.

What did paleomagnetism give strong evidence for?

Paleomagnetism provided strong evidence for plate tectonics, as it revealed that Earth's magnetic field has reversed multiple times throughout history. By studying magnetic minerals in rocks, scientists were able to track the movement of continents and support the theory of plate tectonics.


Rocks that have magnetic fields that point south show?

that they were formed when Earth's magnetic field was reversed, with the magnetic north pole being near the geographic south pole. This phenomenon is known as paleomagnetism and is used to study the history of Earth's magnetic field and plate tectonics.
