Magnetic patterns on the ocean floor were puzzling because they.

On a map of the ocean floor what do the magnetic patterns show. Showed altering bands on of normal and reversed polarity. Why were magnetic patterns found on the ocean floor puzzling. The figure below includes two images of the ocean floor.

The survey data was used to create three dimensional relief maps of the ocean floor and by 1953 american oceanic cartographer marie tharp had created the first of several maps that revealed the presence of an underwater mountain range. Why does this support the theory of plate tectonics. In geophysics a magnetic anomaly is a local variation in the earth s magnetic field resulting from variations in the chemistry or magnetism of the rocks. Where where the youngest rocks on the sea floor.

Tracks of continents plowing through the ocean floor rock. Magnetic patterns are symmetrical on each side of the mid ocean ridge which would indicate that the seafloor is spreading apart like the tectonic plate theory claims. Isacks had integrated this notion of seafloor spreading with that of drifting continents and formulated the basis of plate tectonic theory. Magnetic patterns on the ocean floor were puzzling because they.

The magnetic patterns were a mirror image of each side of the ridge. The ocean floor is thus pushed at right angles and in opposite directions away from the crests. When the earth s magnetic field reverses a new stripe with the new polarity begins. Magnetic patterns on the ocean floor were puzzling because they.

One side is a striped ridge and the other side is the ridge. And that the waves show the magnetic patterns of the sea floor and. The magnetic variation in successive bands of ocean floor parallel with mid ocean ridges is important evidence supporting the theory of. The study paleomagnetism was key in proving wegener s hypothesis because.

Scientists claim that the ocean floor has magnetic patterns. By the late 1960s several american investigators among them jack e. Magnetic patterns on the ocean floor were puzzling because they. Shortly after the conclusion of world war ii sonar equipped vessels crisscrossed the oceans collecting ocean depth profiles of the seafloor beneath them.

Such magnetic patterns led to recognition of the occurrence of sea floor spreading and they remain some of the strongest evidence for the theory of plate tectonics. Oliver and bryan l. That u need to do way more research you stupid but knuckle. It provided evidence of sea floor spreading.
