Magnetic surveys of the ocean floor reveal.
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.
Among the new findings was the discovery of zebra stripe like magnetic patterns for the rocks of the ocean floor.
The concept of seafloor spreading states that.
Seafloor is created at mid ocean ridges and destroyed at deep ocean trenches.
These patterns were unlike any seen for continental rocks.
Newly formed mineral grains on the ocean floor are magnetized according to the new orientation of the magnetic field.
The magnetic variation in successive bands of ocean floor parallel with mid ocean ridges is important evidence supporting the theory of.
Mapping of variation over an area is valuable in detecting structures obscured by overlying material.
D all of the above.
Seafloor is created at mid ocean ridges and destroyed at deep ocean trenches.
Magnetic surveys of the ocean floor reveal.
The concept of seafloor spreading states that.
Magnetic surveys of the ocean floors reveal a alternating stripes of normal and reversed polarity paralleling the mid atlantic ridge.
In a reconstruction of earth s geologic past the continents of africa and south america fit best along the.
C that reversed polarity is rare.
Magnetic surveys of the ocean floor reveal.
Alternating stripes of normal and reversed polarity paralleling the mid atlantic ridge.
Alternating stripes of normal and reversed polarity paralleling the mid atlantic ridge.
B thin oceanic crust composed of basaltic rocks.
