What are magnetic strips on the sea floor caused by?
Movement of the ocean crust
How do strips of magnetized rock on the ocean floor provide evidence of sea-floor spreading?
Strips of ocean-floor basalt record the polarity of earth's magnetic field at the time the rock formed. These strips form a pattern that is the same on both sides of the mid-ocean ridge. the pattern shows that ocean floor forms along mid-ocean ridges and then moves away from the ridge.
Strips of alternating magnetic polarities found in rocks in the ocean basin?
provide evidence for sea-floor spreading
Why are there magnetic strips on the ocean floor what do they mean?
The earth maintains a magnetic field due to the metals that make up its core. Thus, all rocks are influenced by this magnetic field and "face" the direction the field is "facing". Every few hundred million years the poles switch, and with it the magnetic field. Similarly, all rocks "face" the new direction. Magnetic strips are indicators of when the magnetic field of the Earth changed.
Which was not included in the support for harry hess's hypothesis of sea-floor spreading?
Granitic strips in the ocean floor ... Novanet
What are magnetic strips on the floor caused by?
Movement of the ocean crust
What are magnetic strips on the sea floor caused by?

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

Is the ocean floor made out of a pattern of magnetized strips?
Yes, the igneous rocks of the ocean floor exhibit a pattern of oppositely polarized magnetic strips. This demonstrates that the earth's magnetic field has reversed polarity (i.e. swapped north and south poles) several times in the past.

Linear magnetic patterns associated with mid-oceanic ridges are configured as what?
Linear, magnetic patterns associated with mid-ocean ridges are configured as normal and reversed magnetized strips roughly parallel to the ridge. A very long lived magma source located deep in the mantle is called a hot spot.
Need an observation on how magnetic strips disprove plate tectonics on the ocean floor?
I'm wondering the same thing, but all the info I've found shows it supports it.
