Volcanic and other such activity at the mid-Atlantic ridge extrudes material to fill the gap between separating tectonic plates associated with continental drift. The magnetization of rocks is found to reverse in a coordinated manner with distance from the ridge. What does this imply about the Earth’s magnetic field and how could the knowledge of the spreading rate be used to give its historical record?

Respuesta :

Manetho

Answer:

Explained

Explanation:

The magnetization of rocks is found to reverse in a coordinated manner with distance from the ridge.The fact that it implies about the Earth's magnetic field is that the Earth's magnetic Field is able to reverse with time. And if  we know the rate of time for spreading we can find the rate of reversal.
