Magnetic stripes on the sea floor
Explanation:
The observation of magnetic stripes patterns at the region of the Mid-Atlantic Ridge galvanized the evidence that sea floor spreading has been on for several millions of years.
- Geomagnetic field of the earth is similar to that of bar magnet having the north and south pole.
- It originates from the movement of iron-nickel within the outer core.
- This geomagnetic field causes the magnetization of magnetic minerals in rock.
- When freshly formed magma is brought to the surface at the mid oceanic ridge area, the prevailing magnetic field causes the magnetic minerals in the magma to cool in such a way that they align their domains to that of the field.
- The magnetic field of the earth can reverse and take different geometry. Sometimes, its intensity is very strong and at other times it is weak.
- The magnetic minerals in melts bear these records.
- As new materials are brought up, they get magnetized.
