What was not included in the support for Harry Hess's hypothesis of sea floor spreading?
One aspect not included in the support for Harry Hess's hypothesis of sea floor spreading was the lack of direct evidence of the mechanisms driving the process, such as mantle convection. Additionally, the age and magnetic anomalies of the ocean floor were not fully understood at the time, which limited the initial acceptance of his ideas. Furthermore, the concept of plate tectonics, which later provided a comprehensive framework for understanding sea floor spreading, was not yet developed during Hess's proposal in the early 1960s.
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.
How is magnesium used to support the theory of seafloor spreading?
Magnesium is used to support the theory of seafloor spreading because as new oceanic crust forms at mid-ocean ridges, it contains higher levels of magnesium compared to older crust. This can be observed through magnetic anomalies in the oceanic crust, where variations in magnesium content create distinct magnetic stripes that align with the spreading centers. This provides evidence that new crust is being continuously generated at mid-ocean ridges, supporting the process of seafloor spreading.
Which was not included in the support for Harry Hesss hypothesis of sea-floor spreading?
One key piece of evidence not included in support of Harry Hess's hypothesis of sea-floor spreading was the discovery of paleomagnetic data. While Hess's theory focused on the creation of new oceanic crust at mid-ocean ridges and the recycling of crust at subduction zones, the paleomagnetic records provided insights into the historical movement of continents and the magnetic orientation of rocks, which later supported the theory of plate tectonics. Other evidence, such as the age of oceanic crust and the distribution of fossils, played a more direct role in supporting his hypothesis.

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.
What is the most important in providing support for the sea floor spreading hypothesis?
"Magnetic Polarity: the North and South magnetic poles have switched positions throughout Earth's history... the record of magnetic polarity in the rocks of the ocean floor provided unequivical support for the seafloor spreading hypothesis." - as quoted in chp. 4, pg. 94, from the textbook "The Good Earth: Introduction To Earth Science"
How do the ages of the rocks on the ocean floor 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.
How do the ages of rock on the ocean floor 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.
What was not used in support of the continental drift hypothesis?
One key piece of evidence that was not initially used in support of the continental drift hypothesis was a mechanism explaining how continents could move. It wasn't until the discovery of plate tectonics and the development of the theory of seafloor spreading that a mechanism was found to explain how continents drift.

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.
