Answer:
D. magnetic polarity reversals
Explanation:
The marine magnetic anomalies are the result of two things; the seafloor spreading at the mid-ocean ridges and the magnetic polarity reversals.
The mid-ocean ridges are the places where the new crust forms. This places also have big influence on the magnetic anomalies, with the reason being that the magnetism has higher influence in this parts.
Also, the magnetic polarity reversals play a big role. The Earth has not always had the same magnetic polarity, and multiple times throughout its past the North and South Poles have been switching places when it comes to the magnetism.
The igneous rocks on the ocean floor have proof in them about this, as the metallic components are reacting to the magnetism and face toward the stronger magnetic field.
<u>Answer:</u>
The steps which were involved in the impact theory of lunar formation is a <em>prevailing theory of finding which was supported by all the members of the scientist’s community. </em>
<u>Explanation:</u>
The theory suggested and gave an explanation that the lunar formation was origin or formed when bigger objects smashed into earth. Like any other planet the story of formation of earth is also the same.
<em>Earth was just created by the left overs huge masses of cloud dust and the gasses which were orbiting the young sun at that period.</em>
