Earth's magnetic field is mostly created from electric currents caused by material moving in the
A) crust.
B) mantle.
C) outer core.
D) inner core.

Question

Quizplus · Accepted Answer

The Earth's magnetic field is primarily generated by the motion of molten iron in the outer core. This creates electric currents which generate the magnetic field. The crust and mantle also have influence on the magnetic field, but they do not contribute as significantly as the outer core. The inner core is solid iron and nickel, meaning it cannot generate the necessary motion to create the magnetic field.
