Magnetic Surveys Of The Ocean Floor Reveal

These patterns were unlike any seen for continental rocks.

Magnetic surveys of the ocean floor reveal.

Plate tectonics states that. The magnetic variation in successive bands of ocean floor parallel with mid ocean ridges is important evidence supporting the theory of. Magnetic stripes and isotopic clocks oceanographic exploration in the 1950s led to a much better understanding of the ocean floor. 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.

In a reconstruction of earth s geologic past the continents of africa and south america fit best along the. Seafloor is created at mid ocean ridges and destroyed at deep ocean trenches. The concept of seafloor spreading states that. Mapping of variation over an area is valuable in detecting structures obscured by overlying material.

Magnetic surveys of the ocean floor reveal. Seafloor is created at mid ocean ridges and destroyed at deep ocean trenches. Plate tectonics states that. Alternating stripes of normal and reversed polarity paralleling the mid atlantic ridge.
