Magnetic patterns on the ocean floor were puzzling because they.
On a map of the ocean floor what do the magnetic patterns show.
Why does this support the theory of plate tectonics.
Magnetic patterns on the ocean floor were puzzling because they.
The figure below includes two images of the ocean floor.
The survey data was used to create three dimensional relief maps of the ocean floor and by 1953 american oceanic cartographer marie tharp had created the first of several maps that revealed the presence of an underwater mountain range.
By the late 1960s several american investigators among them jack e.
Why were magnetic patterns found on the ocean floor puzzling.
Isacks had integrated this notion of seafloor spreading with that of drifting continents and formulated the basis of plate tectonic theory.
It provided evidence of sea floor spreading.
Magnetic patterns on the ocean floor were puzzling because they.
Magnetic patterns on the ocean floor were puzzling because they.
Magnetic patterns are symmetrical on each side of the mid ocean ridge which would indicate that the seafloor is spreading apart like the tectonic plate theory claims.
Scientists claim that the ocean floor has magnetic patterns.
One side is a striped ridge and the other side is the ridge.
Tracks of continents plowing through the ocean floor rock.
Showed alternating bands of normal and reversed polarity wegener s hypothesis of continental drift was finally confirmed by.
The study paleomagnetism was key in proving wegener s hypothesis because.
Showed altering bands on of normal and reversed polarity.
They were able to sample sea floor rocks they were surprised to find the oldest were only about 160 million years old.
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.
The magnetic variation in successive bands of ocean floor parallel with mid ocean ridges is important evidence supporting the theory of.
The magnetic patterns were a mirror image of each side of the ridge.
Shortly after the conclusion of world war ii sonar equipped vessels crisscrossed the oceans collecting ocean depth profiles of the seafloor beneath them.
That u need to do way more research you stupid but knuckle.
Mapping of variation over an area is valuable in detecting structures obscured by overlying material.
When the earth s magnetic field reverses a new stripe with the new polarity begins.
Magnetic patterns on the ocean floor were puzzling because they.
The ocean floor is thus pushed at right angles and in opposite directions away from the crests.
