1)How to explain the origin of seafloor magnetic anomalies formed at mid ocean ridges?

1)How to explain the origin of seafloor magnetic anomalies formed at mid ocean ridges?


2)what diagram will explain the polarity of the magnetic anomaly at mid ocean ridge consider two cases 1) high magnitude latitude and 2) magnetic equator1)How to explain the origin of seafloor magnetic anomalies formed at mid ocean ridges?
As the floor expands new layers of new floor are polarised it the direction of the earth's magnetic field. As this field changes direction new floor is magnetised in the new direction hence anomalies.
