The magnetic orientation and age of different regions of the seafloor is inferred from the total field intensity using towed magnetometers.

Question

Quizplus · Accepted Answer

This statement is true. The magnetic orientation and age of different regions of the seafloor can be inferred by measuring the total field intensity using towed magnetometers. As seafloor spreading occurs, new crust is formed and the magnetic minerals in the lava align with the Earth's magnetic field at the time of formation. This creates patterns of magnetization that can be detected and used to determine the age of the ocean floor and the direction of the Earth's magnetic field at the time of formation.
