Magnetic Surveys Of The Ocean Floor Reveal

Seafloor is created at mid ocean ridges and destroyed at deep ocean trenches.

Magnetic surveys of the ocean floor reveal.

Plate tectonics states that. 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. D all of the above. Magnetic surveys of the ocean floor reveal.

The magnetic variation in successive bands of ocean floor parallel with mid ocean ridges is important evidence supporting the theory of. B thin oceanic crust composed of basaltic rocks. 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.

Alternating stripes of normal and reversed polarity paralleling the mid atlantic ridge. Magnetic surveys of the ocean floor reveal. Magnetic stripes and isotopic clocks oceanographic exploration in the 1950s led to a much better understanding of the ocean floor. The concept of seafloor spreading states that.

Plate tectonics states that. Seafloor is created at mid ocean ridges and destroyed at deep ocean trenches. These patterns were unlike any seen for continental rocks. Magnetic surveys of the ocean floors reveal a alternating stripes of normal and reversed polarity paralleling the mid atlantic ridge.

The concept of seafloor spreading states that. Magnetic surveys of the ocean floor reveal. Newly formed mineral grains on the ocean floor are magnetized according to the new orientation of the magnetic field.
