Magnetic Patterns On The Ocean Floor Were Puzzling Because They

It provided evidence of sea floor spreading.

Magnetic patterns on the ocean floor were puzzling because they.

The study paleomagnetism was key in proving wegener s hypothesis because. Tracks of continents plowing through the ocean floor rock. It helps them determine the frequency of. 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.

Magnetic patterns on the ocean floor were puzzling because they showed altering bands on of normal and reversed polarity wegeners hypothesis of continental drift was finally confirmed by. The earths magnetic polarity at the time of rock formation. Oliver and bryan l. By the late 1960s several american investigators among them jack e.

Why did scientists expect the ocean floor to have a thick layer of sediment. 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. Isacks had integrated this notion of seafloor spreading with that of drifting continents and formulated the basis of plate tectonic theory. Mapping of variation over an area is valuable in detecting structures obscured by overlying material.

Studying the magnetic patterns of the rocks in the floor of the ocean helps scientists do what. Magnetic patterns on the ocean floor were puzzling because they. The ocean floor is thus pushed at right angles and in opposite directions away from the crests. The magnetic patterns were a mirror image of each side of the ridge.

At spreading centres this crust is separated into parallel bands of rock by successive waves of emergent magma. Why were magnetic patterns found on the ocean floor puzzling. Evidence that was discovered nearly 2 decades after his death. Magnetic patterns on the ocean floor were puzzling because they.

Later theories showed that this was due to the reversing nature of earth s magnetic field. The seafloor was mapped by shipborne magnetometers in the 1950s and produced puzzling results sequential zones of normal and reverse magnetic polarity spreading out from the oceanic ridges.
