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.

BeauMagnetic 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.
When you placed the magnet next to the iron?
nothing will happen dumbazz because it isnt magnetic
What will happen if you place a small compass in a magnetic field?
When a small compass is placed in a magnetic field, the needle of the compass will align itself with the direction of the magnetic field. This is because the needle is magnetized and responds to the magnetic forces in the surrounding area.
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.
