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.

Is it true that the magnetism of the rocks along the ocean floor is consistent in that there is no reversal of polarity?
The rocks of the ocean floor are not consistent and do show past reversal of polarity. The statement in the question is false.
What kinds of magnetism did scientists finds while studying the ocean floor?
While studying the ocean floor, scientists found alternating bands of magnetism. Each band is magnetized with a polarity that is opposite the surrounding bands.
What were found on the ocean floor?
blank are found on the ocean floor
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.
What features are found on the ocean floor?
That it is a topgraphical and the features are a ocean floor.
Magnetic patterns on the ocean floor were puzzling because they?
because they showed alternating bands of normal and reversed polarity.
When Studying the ocean floor scientists found rocks showing what?
Scientists found out about normal polarity and reverse polarity. Normal polarity is when the North Pole is south and the South Pole is north and reverse polarity is the opposite. The magnetic bands are different colors for normal and reverse polarity. This can cause sea-floor spreading.
How did scientists discover that rocks get older from the mid ocean ridge?
They discovered a pattern of reverse and normal polarity in the rock bodies of the ocean floor that indicated that oceanic crust was constantly being formed over time. Polarity shifts in the Earth had already been noted in continental crustal rock. With the advent of radiometric dating, core samples were taken and dated, confirming that the youngest rock is found at the ridge and rock age advances with distance from the ridge.
Why are diatom shells found in ocean-floor sediments?
diatom shells settle on the ocean floor from the surface
Are boundaries always found on the ocean floor?
No, boundaries are found everywhere.
