Explain Why Magnetic Patterns On The Ocean Floor Were Puzzling

Evidence supporting the idea of sea floor spreading.

Explain why magnetic patterns on the ocean floor were puzzling.

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 stripes and isotopic clocks oceanographic exploration in the 1950s led to a much better understanding of the ocean floor. In fact scientists have mapped more of the surface of the moon mars and venus than the surface of our ocean. In 1961 a magnetic survey of the eastern pacific ocean floor off the coast of oregon and california was published by two geophysicists arthur d.

These patterns were unlike any seen for continental rocks. Why were magnetic patterns found on the ocean floor puzzling. When the earth s magnetic field reverses a new stripe with the new polarity begins. Plate tectonics and the ocean floor.

Unlike on the continents where regional magnetic anomaly patterns that is magnetic patterns read more. Why were magnetic patterns found on the ocean floor puzzling. Also the magnetic properties that rock acquires during formation. You may have heard this fact before and while true there is a logical.

All rocks were magnetic. The figure below includes two images of the ocean floor. 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. Evidence that was discovered nearly 2 decades after his death.

Explain why scientists opposed. A history of ocean floor mapping and dating. Among the new findings was the discovery of zebra stripe like magnetic patterns for the rocks of the ocean floor. Mapping of variation over an area is valuable in detecting structures obscured by overlying material.

Raff and ronald g. Closest to the mid ocean ridge. Farthest from the mid ocean ridge. The study of the alignment of magnetic minerals in rock specifically as it relates to the reversal of earths magnetic poles.

The magnetic variation in successive bands of ocean floor parallel with mid ocean ridges is important evidence supporting the theory of. The oldest seafloor is located. Why were magnetic patterns found on the ocean floor puzzling. The magnetic patterns were a mirror image of each side of the ridge.
