As rocks cool past the curie point, they tend to become magnetized in the direction that the earths field is point at that time. The earths magnetic field has reversed many times in the past. The mid ocean ridge is a place where the plates are spreading apart and new hot material is welling up. This makes stripes of rocks that are magnetized in alternating directions.

Is composed of alternating bands of light and dark silicated minerals?
Gneiss shows such banding. Alternating bands are known to Geologists as Gneissose Banding, and is used to instantly classify the metamorphic rock.
What is composed of alternating bands of light and dark silicate minerals?
A gneiss rock is composed of alternating bands of light and dark silicate minerals, typically formed through high temperature and pressure metamorphism of existing rocks like granite or shale. The light bands are usually composed of quartz and feldspar, while the dark bands are made up of minerals like biotite, amphibole, or pyroxene.
What did scientist discovere when they analyzed the magnetic bands on the ocean floor?

What are the bands on Jupiter?
The bands on Jupiter are areas of alternating light and dark clouds that are caused by differences in the planet's atmospheric composition and temperature. The most prominent bands are the equatorial bands and the polar bands, which are visible in Jupiter's atmosphere.
What is the function of buoy that has alternating red and green horizontal bands?
marks the junction of two channels
Combination of alternating dark A bands and light?
The alternation dark and light bands are found in muscles of humans and animals. They give the muscle fibers their striated appearance.
