These stripes often called zebra stripes, due to the alternating colors of the original magnetometer readings. When the first observations were made, it is directly related to two processes geomagnetic reversals and seafloor spreading.
The magnetic stripes on the ocean floor, including those found in seafood areas, are parallel to the mid-ocean ridge due to the process of seafloor spreading. As magma rises at the mid-ocean ridge and solidifies, iron-rich minerals within the magma align with the Earth's magnetic field, creating symmetrical stripes of magnetic polarity on either side of the ridge. This phenomenon occurs over time as new crust is formed and pushes older crust away from the ridge, effectively recording the history of the Earth's magnetic field reversals. Thus, the parallel magnetic stripes are a direct result of the geological processes associated with the mid-ocean ridge.
The magnetic stripes on the seafloor are parallel to the mid-ocean ridge due to the process of seafloor spreading. As magma rises at the mid-ocean ridge and solidifies into new oceanic crust, it records the Earth's magnetic field at the time of its formation. When the magnetic field reverses, new crust is formed with the opposite magnetic orientation, creating symmetrical stripes on either side of the ridge. This pattern reflects the continuous generation of new crust and the periodic flipping of the Earth's magnetic field, leading to the characteristic parallel arrangement.
Yes, the magnetic stripes on the ocean floor provide evidence of the Earth's magnetic pole reversals. As magma rises and solidifies at mid-ocean ridges, iron-rich minerals align with the Earth's magnetic field. When the magnetic field reverses, new stripes form parallel to the ridge, creating a record of past magnetic orientations. This pattern of symmetrical stripes on either side of the ridge supports the theory of plate tectonics and the history of geomagnetic reversals.
As you move away from an ocean ridge, the rocks get older.
Magnetic stripes on the sea floor are parallel to mid-ocean ridges because they form as molten rock at the ridge cools and solidifies, capturing the Earth's magnetic field at that time. As tectonic plates slowly diverge at the ridge, new magma rises and creates new oceanic crust, leading to symmetrical patterns of magnetic reversals on either side of the ridge. This phenomenon is a result of seafloor spreading, which helps scientists understand the history of Earth's magnetic field and plate tectonics.

its the same on either side of the mid-ocean ridge

Mid-Ocean Ridges
The magnetic strips on the sea floor are parallel to the mid-ocean ridge because new oceanic crust is constantly being formed at the ridge due to volcanic activity. As the magma cools and solidifies, it records the Earth's magnetic field orientation at the time. This creates a symmetrical pattern of magnetic strips on either side of the ridge as the Earth's magnetic field reverses over time.
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.
An isochron is a line on a map that connects points that have the same age. An isochron map of the ocean floor supports the theory of seafloor spreading because it shows the older rock near the deep sea trenches and the younger rocks near ocean ridges.
