How does magnetic reversals provide evidence for seafloor spreading?
Because of the stripes at the sea floor which are magnetic minerals
How do magnetic reversals provide evidence of sea - floor spreading?
The presence of magnetic domains of alternating orientation parallel to the plate boundaries.
What do magnetic anomalies provide evidence of?
seafloor spreading
Is the analysis of seafoor sediments evidence of sea-floor spreading?
Not really but sea floor sediments thickness increase with increased distance from spreading centers which is good evidence. Other evidence such as magnetic reversals, temperature, dating methods provide the best evidence of seafloor spreading
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.
How do earths magnetic pole reversals provide evidence for tectonics?
rocks get older as you move away from ocean ridges
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.
How is magnetism used to support the theory about seafloor spreading?
Magnetism is used to support the theory of seafloor spreading through the study of magnetic stripes on the seafloor. These stripes are aligned with the Earth's magnetic field and provide evidence for the process of seafloor spreading, where new oceanic crust is formed at mid-ocean ridges. As the crust cools and solidifies, the magnetic minerals in the rocks align with the Earth's magnetic field, creating a record of magnetic reversals over time that support the theory of seafloor spreading.
Magnetic striping of evidence of?
Magnetic reversals and sea floor spreading.
How do earths magnetic pole reversals provide evidence for plate tectonics?
Magnetic stripes can be seen as you move away from ocean ridges.
