Magnetic Patterns On The Ocean Floor Were Puzzling Because They

On a map of the ocean floor what do the magnetic patterns show.

Magnetic patterns on the ocean floor were puzzling because they.

Why were magnetic patterns found on the ocean floor puzzling. Magnetic patterns on the ocean floor were puzzling because they. That u need to do way more research you stupid but knuckle. Where where the youngest rocks on the sea floor.

Isacks had integrated this notion of seafloor spreading with that of drifting continents and formulated the basis of plate tectonic theory. 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. Showed alternating bands of normal and reversed polarity wegener s hypothesis of continental drift was finally confirmed by. Showed altering bands on of normal and reversed polarity.

Mapping of variation over an area is valuable in detecting structures obscured by overlying material. The magnetic variation in successive bands of ocean floor parallel with mid ocean ridges is important evidence supporting the theory of. It provided evidence of sea floor spreading. One side is a striped ridge and the other side is the ridge.

Shortly after the conclusion of world war ii sonar equipped vessels crisscrossed the oceans collecting ocean depth profiles of the seafloor beneath them. When the earth s magnetic field reverses a new stripe with the new polarity begins. They were able to sample sea floor rocks they were surprised to find the oldest were only about 160 million years old. The magnetic patterns were a mirror image of each side of the ridge.

Why does this support the theory of plate tectonics. And that the waves show the magnetic patterns of the sea floor and. 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. Magnetic patterns on the ocean floor were puzzling because they.

The figure below includes two images of the ocean floor. By the late 1960s several american investigators among them jack e. Magnetic patterns on the ocean floor were puzzling because they. The study paleomagnetism was key in proving wegener s hypothesis because.

Oliver and bryan l. The ocean floor is thus pushed at right angles and in opposite directions away from the crests. 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. Magnetic patterns on the ocean floor were puzzling because they.
