* Excerpt from Wikipedia
It indicates that the crust is growing equally over time on either side of a mid-ocean divergent plate boundary. The magnetic orientation indicates the direction of the magnetic pole at the time the rock's magnetic minerals solidified from lava or magma.
that u need to do way more research you stupid but knuckle. and that the waves show the magnetic patterns of the sea floor and that the magnitude causes most typhoons and do to underground earthquakes.
Evidence of seafloor spreading

"Stripes" of alternating magnetic field in the basalt rock of the seafloor.
rocks get older as you move away from ocean ridges
Magnetic stripes can be seen as you move away from ocean ridges.
As mid ocean ridges create new seafloor over extended periods of time, the magnetic poles of the Earth reverse back and forth. The rocks on either side of a mid ocean ridge show the opposite magnetisms and appear striped. From knowing the approximate ages of these magnetic reversals, one can estimate the approximate age of each stripe.

The direction of the Earth's magnetic field has reversed several times during its history. This causes the North magnetic pole to become a South magnetic pole and vice versa. We know this because of the direction of magnetism in the rocks on the ocean floor, which alternates in 'stripes' on either side of the mid-ocean ridges.

The Earth's magnetic reversals have been recorded in newly forming oceanic seafloor basalt by the orientation of magnetic minerals which become frozen in place as the magma hardens. When the next reversal occurs, it as well becomes part of the ocean floor magnetic record.

The pattern only appears in images of magnetic field intensity, not really visible. Caused by changes in Earth's magnetic field over time especially reversals of the magnetic poles. "Stripes" represents different ages of rocks as they spread from mid-ocean ridges. Magnetic properties of lavas are set when they cool down and minerals such as magnetite crystallize.
