Answer:
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.

Answer:
The correct answer is option a. "Cross-sectional study".
Explanation:
A cross-sectional study is a type of observational study used in medical and social researches. Cross-sectional studies are characterized by the analysis of data that comes from a population at a specific point of time. A research that involves studying the incidence of cholera carriers at three different villages with three different types of water supply, is an example of a cross-sectional study.
