Iron gains magnetism at a certain temperature known as the curie point. at this point Iron rich minerals align with the magnetic polls. Today Iron minerals have been found in older rocks pointing in a variety of directions and since our polls do not move this provided evidence that the Continents containing those minerals have moved and after lining up these magnetic rocks with others from the same time they all correlate with Continental drift and plate tech-tonics.

Why do Earth's magnetic pole reversals provide evidence for plate tectonics?
Earth's magnetic pole reversals are recorded in rocks as they cool and solidify. When rocks form, they preserve the orientation of Earth's magnetic field at that time. By studying the magnetic alignment of rocks on the ocean floor, scientists have discovered patterns that support the theory of plate tectonics, such as the symmetrical magnetic striping on either side of mid-ocean ridges.
How do earths magnetic pole reversals provide evidence for plate tectonics?
Magnetic stripes can be seen as you move away from ocean ridges.
How do earths magnetic pole reversals provide evidence for tectonics?
rocks get older as you move away from ocean ridges

Strips of alternating magnetic polarities found in rocks in the ocean basins?
They are known as magnetic stripes and are formed as new sea floor is created at mid-ocean ridges. When molten rock solidifies, it preserves the direction of Earth's magnetic field at that time, creating a record of magnetic reversals in the oceanic crust. The alternating stripes of normal and reversed polarity provide evidence for seafloor spreading and plate tectonics.
Why do earth magnetic pole reversals provide for plate tectonics?
Rocks lock in their magnetism when they cool.

How does magnetic reversals provide evidence for seafloor spreading?

What do magnetic reversals provide strong evidence of?
Magnetic reversals provide strong evidence of the Earth's shifting magnetic field over geological time scales. These reversals, recorded in the ocean floor's basaltic rocks, support the theory of plate tectonics by demonstrating seafloor spreading and continental drift. The patterns of magnetic striping on either side of mid-ocean ridges show symmetrical changes in polarity, reinforcing the idea of new crust being formed and pushed away from these divergent boundaries. This evidence is crucial for understanding the dynamic processes that shape our planet.
Magnetic reversals provide strong evidence for what at the bottom of the ocean?
Magnetic reversals provide strong evidence for the process of seafloor spreading at the bottom of the ocean. As magma rises and solidifies at mid-ocean ridges, it records the Earth's magnetic field direction, which periodically reverses. This creates a pattern of magnetic stripes on either side of the ridge, demonstrating how new oceanic crust is formed and pushed away from the ridge over time. These patterns serve as key evidence for the theory of plate tectonics.
How magnetic reversals provide evidence for sea floor spreading?
Because of the stripes at the sea floor which are magnetic minerals
How do ocean basin magnetic reversals prove plate tectonics exists?
They technically don't. They do provide evidence for it, however, in that they occur in pairs on either side of a rift, providing strong evidence that the rocks on either side were deposited at the same time and that the rifts are spreading.
