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.
Midocean ridges are areas where continents broke apart. Midocean ridges are closest to the landmasses in younger oceans. One example where a midocean ridge intersected a landmass is the Arabian sea, which was formed by the pulling apart of the Arabian Peninsula and Africa.
One of the midocean ridges is, but others are in other oceans, seas, and bays.

Friction ridge patterns are unique patterns created by raised skin ridges found on the palms of the hands and soles of the feet. These patterns include loops, whorls, and arches, which are used for fingerprint identification.
They discovered a pattern of reverse and normal polarity in the rock bodies of the ocean floor that indicated that oceanic crust was constantly being formed over time. Polarity shifts in the Earth had already been noted in continental crustal rock. With the advent of radiometric dating, core samples were taken and dated, confirming that the youngest rock is found at the ridge and rock age advances with distance from the ridge.

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.
The pattern of magnetic striping on one side of the ridge was a mirror image of the striping on the other side of the ridge, indicating that the plates were moving equally in opposite directions, giving a plausible explanation for continental drift theory. Before this discovery, no evidence of a mechanism for plate tectonics existed. It was obvious after this discovery, that new crust was being created at the ridges.

Older, as it moves away from the mid-ocean ridge the sediment gets thicker and older
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.
The mid ocean ridge separates many plates, not just two. In the Atlantic Ocean it separates the Eurasian and African plates from the North American Plate and the African Plate from the South American Plate. In the Indian Ocean it separates the African Plate from the Antarctic, Australian, Indian Plates and the Australian Plate from the Antarctic Plate. In the Red Sea it separates the African Plate from the Arabian Plate. In the Pacific Ocean it separates the Pacific Plate from the Antarctic, Nazca, Cocos, and Juan de Fuca Plates and the Nazca Plate from the Cocos and Antarctic Plates.
The midocean ridges are the spreading centers where the plates are moving apart. The seamounts are extinct volcanos produced as the plate passed over a mantle hotspot.
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.
Color patterns are generally a dark brown base with pale or white horizontal striping, but vary slightly between subspecies.
