Magnetic patterns on the ocean floor were puzzling because they?
because they showed alternating bands of normal and reversed polarity.
Why are magnet patterns important evidence for plate tectonics?
magnetic rocks on the ocean floor show that the Earths magnetic field has been frequently reversed forming new sea floor.
Studying the magnetic patterns of the rocks in the floor of the ocean helps scientists do what?
It helps them determine the frequency of shifts in the magnetic orientation of the Earth, and initially led to the confirmation of seafloor spreading at the mid-ocean ridges.
What are magnetic strips on the sea floor caused by?
Movement of the ocean crust
What is the significance of the patterns of offsets along mid-ocean ridges?
the matching patterns on either side of the mid-ocean ridge could be explained by new ocean crust forming at the ridge and spreading away from it as ocean crust forms it obtains the polarity of the earth's magnetic field at that time over time the strength of the earths magnetic field changes when new ocean crust forms at the center of the spreading it obtains a new kind of magnetic polarity over time a series of magnetic ''stripes'' are formed

What is sea floor spreading and what evidence do we have to prove it is happening?
Magnetic minerals on the ocean floor.
What are magnetic strips on the floor caused by?
Movement of the ocean crust
Is there magnetic strips on the ocean floor are places where oceanic crust sink back to the mantle?
Is there magnetic stripe son the ocean floor are places where oceanic crust sink back to the mantle
Vine and Matthews determined that new ocean floor was being produced at ocean ridges by examing?
the magnetic pattern on the sea floor
What are magnetic strips on the sea floor caused by?
Movement of the ocean crust
The magnetic record in the rock on the ocean floor depends on when the rock was?
i dont know
Are magnetic stripes visible earths ocean floor?

What feature on the ocean floor does the lines on the strips represent?
It represents the pattern of the magnetic strip.
