Magnetic Patterns On The Ocean Floor Were Puzzling Because They

Why did scientists expect the ocean floor to have a thick layer of sediment.

Magnetic patterns on the ocean floor were puzzling because they.

Showed alternating bands of normal and reversed polarity wegener s hypothesis of continental drift was finally confirmed by. 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. Tracks of continents plowing through the ocean floor rock. 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.

Why were magnetic patterns found on the ocean floor puzzling. It provided evidence of sea floor spreading. Oliver and bryan l. 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. At spreading centres this crust is separated into parallel bands of rock by successive waves of emergent magma. Studying the magnetic patterns of the rocks in the floor of the ocean helps scientists do what. The earths magnetic polarity at the time of rock formation.

Magnetic patterns on the ocean floor were puzzling because they. By the late 1960s several american investigators among them jack e. The ocean floor is thus pushed at right angles and in opposite directions away from the crests. 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.

Magnetic patterns on the ocean floor were puzzling because they. The study paleomagnetism was key in proving wegener s hypothesis because. 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. Isacks had integrated this notion of seafloor spreading with that of drifting continents and formulated the basis of plate tectonic theory.

Evidence that was discovered nearly 2 decades after his death. The magnetic patterns were a mirror image of each side of the ridge.
