The Mid Ocean Ridge would have magnetic striping. As the seafloor expands, new oceanic crust is spread in either direction. As this process continues over many years, the magnetic poles may switch, altering the magnetism in the new crust. The poles will switch back and forth, producing the magnetic striping that is easily discernible when examining the Mid Ocean Ridge and surrounding seafloor.
What else can I help you with?
What structure on the seafloor would have magnetic striping?
A mid-ocean ridge would have magnetic striping on the seafloor. This striping is caused by the alternating polarities of Earth's magnetic field recorded in the basaltic rocks as they cool and solidify at the mid-ocean ridge, providing evidence for seafloor spreading.
What pattern of striping at a mid ocean ridge would you expect to find?
At a mid-ocean ridge, you would expect to find a symmetrical pattern of magnetic striping on either side of the ridge. This pattern results from the periodic reversal of Earth's magnetic field, which causes new basaltic rock formed at the ridge to record the current magnetic orientation as it cools. As tectonic plates move apart, these magnetic stripes mirror each other on both sides of the ridge, providing evidence for seafloor spreading. The age of the stripes increases with distance from the ridge, supporting the theory of plate tectonics.
How would the history of reversals show itself on the ocean floor?
The history of reversals can be observed on the ocean floor through magnetic striping. When new oceanic crust is formed at mid-ocean ridges, magnetic minerals align with the Earth's magnetic field. Over time, as the Earth's magnetic field reverses, these minerals record the reversals in alternating magnetic stripes on the ocean floor. This provides evidence for the history of reversals.
What pattern of striping at a mid-ocean ridge would you expect to find?
At a mid-ocean ridge, you would expect to find a symmetrical pattern of striping on either side of the ridge. This pattern is created by the process of seafloor spreading, where new oceanic crust is formed as magma rises and solidifies at the ridge. As the tectonic plates move apart, magnetic minerals in the newly formed rock align with the Earth's magnetic field, resulting in alternating bands of normal and reversed magnetic polarity. This pattern is mirrored on both sides of the ridge, providing evidence for the age of the oceanic crust and the history of geomagnetic reversals.
What if earths magnetic field was fixed in place and the polarity didn't reverse what effect would this have on our observations of seafloor basalts?
If Earth's magnetic field was fixed without reversals, newly-formed seafloor basalts would only show one magnetic orientation. This uniformity would make it harder to track the movement of tectonic plates or determine the age of the seafloor using magnetic stripes. It would also impact our understanding of plate tectonics and Earth's geology.
Imagine that Earth and acirc and 128 and 153s magnetic field was fixed in place and the polarity didn't reverse. What effect would this have on our observations of seafloor basalts?
If Earth's magnetic field was fixed in place and did not reverse polarity, seafloor basalts would display a consistent magnetic orientation, making it more challenging to track long-term changes in Earth's magnetic field. This could impact our ability to study plate tectonics, as we rely on changes in magnetic polarity recorded in seafloor basalts to understand the movement of tectonic plates over time.
What pattern of striping at a mid ocean ridge would you expected find if the magnetic polarity changed many times over a short period?
If magnetic polarity changed many times over a short period at a mid-ocean ridge, you would expect to find a complex pattern of striping on either side of the ridge. Instead of the typical symmetrical, alternating bands of normal and reversed polarity, the stripes would appear irregular and fragmented, indicating rapid and multiple reversals. This chaotic pattern would reflect the tumultuous geological activity in the area, complicating the interpretation of the magnetic history. Overall, the striping would likely be less distinct and more varied than in areas with more stable magnetic reversal timelines.
How would you use retain in a sentence?
struture means a building.
What would it be like if earth had no magnetic fields?
Devoid of life, as the magnetosphere is what prevents the solar winds from striping the planet of atmosphere and destroying all life by irradiation. Compasses would also cease working.
How would the history of magnetic reversals show it self on the ocean floor?
It indicates that the crust is growing equally over time on either side of a mid-ocean divergent plate boundary. The magnetic orientation indicates the direction of the magnetic pole at the time the rock's magnetic minerals solidified from lava or magma.
Why is striping spelled with one P?
If I am referring to stripes then it would be striping. Example: I am striping this object with paint. Stripping with two p's refers to an act of removing one's clothes. Example: I am stripping off my work clothes to change into my pajamas.
What do scientists now know about earth that would have answered the scientists who rejected wegeners theory?
Scientists now know about plate tectonics, which explains how Earth's outer shell is divided into large plates that move and interact with each other. This understanding supports Wegener's theory of continental drift, as it provides a mechanism for the movement of continents over time. Additionally, evidence from ocean floor mapping, seafloor spreading, and magnetic striping further supports the concept of plate tectonics.
