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.
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.
What do magnetic anomalies provide evidence of?
seafloor spreading
Which of these does NOT provide some evidence for plate tectonics?
We don't answer questions from printed/copyrighted materials.
What is proof of theory of plate tectonics developed?
The theory of plate tectonics is supported by evidence such as the matching coastlines of continents, distribution of earthquakes and volcanoes along plate boundaries, and the mapping of magnetic striping on the ocean floor. Additionally, studies of mid-ocean ridges and subduction zones provide further evidence for the movement of Earth's lithospheric plates.

How do earths magnetic pole reversals provide evidence for plate tectonics?
Magnetic stripes can be seen as you move away from ocean ridges.
Strips of alternating magnetic polarities found in rocks in the ocean basins .?
provide evidence for sea-floor spreading
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.
What do magnetic anomalies provide evidence of?
seafloor spreading
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.
What are some features of the ocean floor that provide evidence for plate tectonics?
they found fossils
Which of these does NOT provide some evidence for plate tectonics?
We don't answer questions from printed/copyrighted materials.
What are magnetic stripes on the seafloor?
Magnetic stripes on the seafloor are alternating bands of magnetized rock that form parallel to mid-ocean ridges. These stripes are a result of Earth's magnetic field changing direction over time and getting preserved in the rocks as they cool and solidify. They provide evidence for seafloor spreading and plate tectonics.

What can minerals in rocks show that provide evidence for plate tectonics?
I can't find it in my packet either.
