The magnetic pattern of ocean floor rocks on one side of an ocean ridge is a mirror image of that of the other side isochron maps of the seafloor indicate that ocean crust is.
The magnetic pattern of ocean floor rocks on one side of an ocean ridge is.
When geologists determined the ages of the rocks in the magnetic reversal bands on either side of mid ocean ridges they found that the rocks at the center of a mid ocean ridge are the youngest.
Alternating stripes of magnetically different rock were laid out in rows on either side of the mid ocean ridge.
Youngest near ocean ridges isochron maps of the seafloor indicate that ocean crust is.
At right angles to the ocean ridge.
Much different from the magnetic pattern found in rocks on land d.
The magnetism of mid ocean ridges helped scientists first identify the process of seafloor spreading in the early 20th century.
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.
A vast underwater mountain chain is called a n.
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.
The rocks on either side of a mid ocean ridge record the direction of the earth s magnetic field at the time they were formed and form a pattern of magnetic stripes on either side of the ridge.
One stripe with normal polarity and the adjoining stripe with reversed polarity.
Younger than on the other side c.
A n is used to measure and record the magnetic signature of the rocks on the seafloor.
These patterns of stripes provide the history of seafloor spreading.
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.
174 unit 3 dynamic earth m agnetic north magnetic north bands of rocks on both.
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 theory of explains how new crust is.
This creates a symmetrical pattern of magnetic stripes of opposite polarity on either side of mid ocean ridges.
A mirror image of that of the other side.
The magnetic pattern of ocean floor rocks on one side of an ocean ridge is a mirror image of that of the other side.
