What variables could influence the width of marine magnetic anomalies on the floor of the ocean?

Duration of the magnetic polarity event

Rate at which the plates are moving away from the mid-ocean ridge

Explanation:

The marine magnetic anomaly usually refers to the variation that occurs in terms of the magnetic field strength of the earth. This takes place because of the presence of minerals within the rocks of seafloor that contains high magnetic property.

These magnetic anomalies occurring in the marine rocks cover only about 1% of the total strength of the geomagnetic field. It shows either positive or negative anomaly.

Some of the factors that influence the width of this marine magnetic anomalies on the rocks of ocean-floor includes:

The amount of time it takes during the magnetic polarity event The rate at which the tectonic plates move at a divergent plate boundary from the mid-oceanic ridge.
