Explain Why Magnetic Patterns On The Ocean Floor Were Puzzling

You may have heard this fact before and while true there is a logical.

Explain why magnetic patterns on the ocean floor were puzzling. In fact scientists have mapped more of the surface of the moon mars and venus than the surface of our ocean. Among the new findings was the discovery of zebra stripe like magnetic patterns for the rocks of the ocean floor. The magnetic variation in successive bands of ocean floor parallel with mid ocean ridges is important evidence supporting the theory of. Bathymetry the shape of the ocean floor is largely a result of a process called plate tectonics the outer rocky layer of the earth includes about a dozen large sections called tectonic plates that are arranged like a spherical jig saw puzzle floating on top of the earth s hot flowing mantle.

A history of ocean floor mapping and dating. The figure below includes two images of the ocean floor. The ocean floor is a mysterious place that marine geologists and oceanographers have struggled to fully grasp. All rocks were magnetic.

Why were magnetic patterns found on the ocean floor puzzling. The magnetic patterns were a mirror image of each side of the ridge. Raff and ronald g. They did not show alternating bands of normal and reversed polarity.

Closest to the mid ocean ridge. Evidence supporting the idea of sea floor spreading. Evidence that was discovered nearly 2 decades after his death. 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.

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. When the earth s magnetic field reverses a new stripe with the new polarity begins. These patterns were unlike any seen for continental rocks. Unlike on the continents where regional magnetic anomaly patterns that is magnetic patterns read more.

Mapping of variation over an area is valuable in detecting structures obscured by overlying material. 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. Why were magnetic patterns found on the ocean floor puzzling.

Plate tectonics and the ocean floor. Explain why scientists opposed. Magnetic stripes and isotopic clocks oceanographic exploration in the 1950s led to a much better understanding of the ocean floor. The oldest seafloor is located.
