Magnetic Patterns On The Ocean Floor Were Puzzling Because They

It helps them determine the frequency of.

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. 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. The study paleomagnetism was key in proving wegener s hypothesis because.

Magnetic patterns on the ocean floor were puzzling because they. It provided evidence of sea floor spreading. The magnetic patterns were a mirror image of each side of the ridge. The magnetic variation in successive bands of ocean floor parallel with mid ocean ridges is important evidence supporting the theory of.

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. At spreading centres this crust is separated into parallel bands of rock by successive waves of emergent magma. Tracks of continents plowing through the ocean floor rock. Why were magnetic patterns found on the ocean floor puzzling.

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. 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. Later theories showed that this was due to the reversing nature of earth s magnetic field.

By the late 1960s several american investigators among them jack e. Evidence that was discovered nearly 2 decades after his death. The earths magnetic polarity at the time of rock formation. When earth s geomagnetic field undergoes a reversal the change in polarity is recorded in the magma which contributes to the alternating pattern of magnetic striping on the seafloor.

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.
