The theory of explains how new crust is.
Magnetic pattern of ocean floor rocks on one side of an ocean ridge is.
When these magnetic patterns were mapped over a wide region the ocean floor showed a zebra like pattern.
A mirror image of that of the other side b.
Alternating stripes of magnetically different rock were laid out in rows on either side of the mid ocean ridge.
Basalt the once molten rock that makes up most new oceanic crust is a fairly magnetic substance and scientists began using magnetometers to measure the magnetism of the ocean floor in the 1950s what they discovered was that the magnetism of the ocean floor around.
The magnetic pattern of ocean floor rocks on one side of an ocean ridge is a mirror image of that of the other side.
In the ocean floor the magnetization was orderly arranged in long strips.
Much different from the magnetic pattern found in rocks on land d.
At the mid ocean ridge spreading axis these flips in the direction of the earth s magnetic field are recorded in the magnetization of the lava.
A mirror image of that of the other side.
These patterns of stripes provide the history of seafloor spreading.
This creates a symmetrical pattern of magnetic stripes of opposite polarity on either side of mid ocean ridges.
That were currently present in the are the presences of similar.
One stripe with normal polarity and the adjoining stripe with reversed polarity.
A n is used to measure and record the magnetic signature of the rocks on the seafloor.
A vast underwater mountain chain is called a n.
This dence colder seafloor begins to sink helping to form the mid ocean ridge.
Isochron maps of the seafloor indicate that ocean crust is youngest near ocean ridges.
The magnetic pattern of ocean floor rocks on one side of an ocean ridge is.
The magnetic pattern of ocean floor rocks on one side of an ocean ridge is.
The strips on the atlantic ocean floor in particular all seemed parallel to the mid atlantic ridge that is a volcanic ridge running roughly north to south with some zigs and zags halfway between europe africa and america.
The magnetic pattern of raocean floor rocks on one side of an ocean ridge is a.
As the new sea floor moves awat form the ridge it cools contracts and becomes denser than the material below it.
At right angles to the ocean ridge.
Younger than on the other side c.
