Why is the zebra like pattern seen in the magnetic signature of mid Atlantic ridges?
Wiki User
∙ 11y ago
The pattern is caused by the magnetic alignment of certain iron minerals in solidifying magma with Earth's magnetic field at the time of the magma's solidification. Earth's magnetic field has not been static over geologic time, and its shifts are recorded in the igneous rock produced at the Mid-Atlantic ridge.

The seafloor magnetic pattern is best described as?
parallel to and symmetric about ocean ridges
What causes the magnetic striping noticed about the mid ocean ridges?
These "stripes" formed the pattern known as magnetic striping. ... They hypothesized that the magnetic striping was produced from the generation of magma at mid-ocean ridges during alternating periods of normal and reversed magnetism by the magnetic reversals of the Earth's magnetic field.
How do earths magnetic pole reversals provide evidence for plate tectonics?
Magnetic stripes can be seen as you move away from ocean ridges.
Vine and Matthews determined that new ocean floor was being produced at ocean ridges by examing?
the magnetic pattern on the sea floor
Where are magnetic bands formed to ocean ridges?
It's formed in magma before it is oozed up through the ocean floor at the Mid-Atlantic Ridge. While it is still liquid, the iron molecules in the lava can orient themselves along the magnetic lines of force that envelope the earth.
The pattern of magnetic reversals along the sides of mid-ocean ridges resembles?
Stripes on a zebra. I would know since I had this same question on an assignment. :)
How are mid Atlantic ridges formed?
It was formed when there was linear gap formed below at the ocean floor... So when the hot magma came out from it, it began to cool and solidify forming mid atlantic ridges
How are the mid-Atlantic ridges formed?

The magnetic particles in seafloor ridges are aligned differently in a repeating pattern How does this provide evidence for tectonic movement Why does it provide evidence?
Earth's magnetic field reverses over time; the changes show that seafloor has taken place over time.
What has casued the zebra pattern in the rock of the ocean floor?
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.
What a sentence using mid ocean ridge?
mid Atlantic ridges
What motion of the sea floor is responsible for the formation of the mid Atlantic ridges rift valley?
According to scientists, the process associated with seafloor spreading is responsible for the formation of the mid Atlantic ridges rift valley.
