Scientist suggest that the movement of Earth's liquid iron core results in electrical currents. These currents would then result in Earth's magnetic field. Recent satellite data suggest that the strength of Earth's magnetic field has weakened by about 3.5 percent in some areas. In other areas, Earth's magnetic field strength has increased by about 2 percent. Which statement best explains the differences in Earth's magnetic field strength based on the movement of Earth's liquid iron core?

The movement of Earth's liquid iron core stopped in both locations.

The movement of Earth's liquid iron core changes direction in some locations.

The movement of Earth's liquid iron core is the same in all locations

The movement of Earth's liquid iron core increased speed in both locations.
