The creation of the magnetic field of Earth is thought to be influenced by
A) a magnetized solid iron core in Earth's interior.
B) the flow of solar wind particles around and within Earth's outer atmospheric region, the magnetosphere, which produces an equivalent electric current.
C) electric currents flowing in the electricity-conducting liquid core of Earth.
D) localized magnetic anomalies, frozen into place in the crust near Earth's surface.

Question

Quizplus · Accepted Answer

The creation of Earth's magnetic field is primarily attributed to electric currents flowing in its liquid outer core. This process is known as the geodynamo. The movement of the electrically conductive molten iron and nickel generates these currents, which in turn produce the magnetic field.
