The plate tectonics based theory ha a three pronged aproach; both the zebra-like magnetic striping and the construction of the mid-ocean ridge system, the seafloor spreading hypothesis (SFS) quickly gained converts and represented another major advance in the development of the plate-tectonics theory. Furthermore, the oceanic crust now came to be appreciated as a natural "tape recording" of the history of the geomagnetic field reversals (GMFR) of the Earth's magnetic field. Nowadays, extensive studies are dedicated to the calibration of the normal-reversal patterns in the oceanic crust on one hand and known timescales derived from the dating of basalt layers in sedimentary sequences (magnetostratigraphy) on the other, to arrive at estimates of past spreading rates and plate reconstructions.

Magnetic striping happens when molten rock solidifies and the magnetic minerals within it align themselves with the Earth's magnetic field. As the rock cools and hardens, it preserves a record of the Earth's magnetic polarity at that time. This phenomenon helps scientists study the history of the Earth's magnetic field and the movement of tectonic plates.

What Causes of magnetic striping?

Magnetic striping on the ocean floor is caused by the movement of tectonic plates. As new oceanic crust is formed at mid-ocean ridges, Earth's magnetic field causes iron-rich minerals in the crust to align and record the direction of the magnetic field at that time. This results in alternating patterns of magnetic polarity stripes on the ocean floor.


What is the relationship between the ages of magnetic stripes and their distance from the ridge crest?

Magnetic stripes that are closer to the ridge crest tend to be younger, while those further away are older. This is because new crust is continually formed at the ridge crest through sea floor spreading, with magnetic minerals aligning themselves with Earth's magnetic field as they solidify, creating the alternating pattern of magnetic striping.

What happen to the magnetic flux when it passes through a ferro-magnetic substance?

When magnetic flux passes through a ferromagnetic substance, the substance can become significantly magnetized. This is due to alignment of magnetic domains within the material, enhancing the overall magnetic effect. Ferromagnetic materials have a high magnetic permeability compared to non-magnetic materials, allowing them to concentrate magnetic lines of force.


What must happen in order electric charges to produce a magnetic field?

Electric charges must be in motion to produce a magnetic field. When electric charges move, they generate a magnetic field around them. The strength of the magnetic field depends on the speed and direction of the moving charges.

What causes the magnetic striping noticed about the mid ocean ridges?

These "stripes" formed the pattern known as magnetic striping. ... They hypothesized that the magnetic striping was produced from the generation of magma at mid-ocean ridges during alternating periods of normal and reversed magnetism by the magnetic reversals of the Earth's magnetic field.

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 struture on the seafloor would have magnetic striping?

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.

Magnetic striping is a part of?

Magma contains many materials which are magnetically affected. When this magma is ejected from the mantle and begins forming new crust, these materials align to the earth's magnetic field. The crust hardens, and the magnetic alignment is fixed (just as in normal magnets, made by using a similar process). The magnetic fields are 'visile' in strips of material, hence the term 'magnetic striping'. seafloor spreading


What concepts did magnetic striping reveal to scientists about the rock on either side of a spreading ridge?

Magnetic striping revealed that the rock on either side of a spreading ridge is symmetrical and parallel. This indicated seafloor spreading and demonstrated that new oceanic crust is formed at mid-ocean ridges as magma solidifies and creates a record of Earth's changing magnetic field over time.
