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.


How do the ages of the rocks on the seafloor support the theory of seafloor spreading?

The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.

Granitic strips in the ocean floor ... Novanet


How does seafoor age and magnetic clues support seafloor spreading?

Seafloor is youngest near the mid-ocean ridges and gets progressively older as you move away from the ridge. Magnetic stripes on the seafloor provide evidence of seafloor spreading, as they show alternating patterns of normal and reversed magnetic polarity that match the Earth's magnetic reversals over time. This supports the theory of seafloor spreading as new oceanic crust is created at the mid-ocean ridge and spreads outward.


Who were the two scientists who proposed the theory of seafloor spreading in early 1960s?

While two people proposed continental drift (Alfred Wegener and Alexander du Toit), it was just ONE scientist Harry Hess that proposed the mechanism of sea floor spreading to explain how the continents actually moved.

How did research from the Glomar challenge help scientist support the theory of seaflooding spreading?

From Wikipedia: Starting from August 1968, the Glomar Challenger embarked on a year-long scientific expedition, the Deep Sea Drilling Program, criss-crossing the Mid-Atlantic Ridge between South America and Africa and drilling core samples at specific locations. When the age of the samples was determined by paleontological and isotopic dating studies, this provided conclusive evidence for the seafloor spreading hypothesis, and, consequently, for continental drift.


How did the new evidence support Hess's theory of seafloor spreading?

The new evidence provided observations of magnetic anomalies on the seafloor that were consistent with the pattern predicted by Hess's theory of seafloor spreading. These anomalies demonstrated symmetrical stripes of magnetic polarity on either side of mid-ocean ridges, supporting the idea that new oceanic crust was forming at these ridges and moving away in opposite directions.

How seismic studies support seafloor spreading?

Seismic studies show evidence of mid-ocean ridges where new oceanic crust is forming, supporting the theory of seafloor spreading. By analyzing seismic waves, scientists can map the structure of the ocean floor and identify areas of tectonic activity where plates are moving apart. Additionally, seismic data reveals the presence of magnetic striping on the seafloor, further supporting the idea of seafloor spreading.
