What causes Magnetic stripes on the seafloor are caused by?
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.
What is seafloor spreading called?
It is part of continental drift and plate tectonics.
What part of an electric fan makes a magnetic field?
a motor
What part of an atom is responsible for producing magnetic fields?
electrons
What is the layer in which the magnetic field of the Earth is produced?
The outer liquid core produces the strong magnetic field of the Earth, through the dynamo effect.
What Magnetic stripes on the seafloor are caused on part by?
movement of ocean crust.
Why do magnetic strips appear on seafloor?
Magnetic strips appear on the seafloor because it spreads apart, forming new rocks that have a magnetic properties.

How a prediction and then evidence of magnetism in rocks on the ocean floor proved that the seafloor spreads?
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.

How does the mid ocean ridge magnetic signal prove sea floor spreading?
New oceanic crust is being created at the mid-ocean rift zones, a global divergent plate boundary system where uprising magma fills in the spaces being created by the pulling apart of plates. Part of the newly forming crust follows the direction of one plate, and part of the newly forming crust follows the direction of the other plate; therefore, the age of the rock created from the magma has a mirror image on either side of the rift. As new oceanic crust is continuously being formed at the mid-ocean ridges by upwelling molten rock, the direction of Earth's magnetic field is recorded in the rock by the orientation of magnetic minerals, which align themselves in the direction of the magnetic field before the rock completely crystallizes. Earth's magnetic field is known to change its orientation with frequency on a geologic time scale, thus a pattern of stripes of magnetic orientation is formed which can be detected with a magnetometer. The discovery of magnetic stripes on the seafloor have allowed researchers to provide additional proof that new crust is being created, and that magnetic reversals have occurred and will occur in the future. They tell us that over the course of thousands of years, Earth's polarity will reverse itself. The stripes are the magnetic "footprint" of Earth's shifting magnetic field.
Magnetic striping is a part of?
Magma contains many materials which are magnetically affected. When this magma is ejected from the mantle and begins forming new crust, these materials align to the earth's magnetic field. The crust hardens, and the magnetic alignment is fixed (just as in normal magnets, made by using a similar process). The magnetic fields are 'visile' in strips of material, hence the term 'magnetic striping'. seafloor spreading
What part of word is stripes?
The word stripes is a noun.
What does magma have to do with seafloor spreading?
When seafloor spreading occurs, it pushes the underground magma up though the new crust, creating a sort of volcano out of the new crust. Magma is a very important part in seafloor spreading. :]
What is seafloor spreading called?
It is part of continental drift and plate tectonics.
Is a magnetic pole the part of a magnet where the magnetic effect is the weakest?
A magnetic pole is where the magnetic effect is greatest.
