GIVING BRAINLIEST Which statement best explains how Earth's magnetic field is generated? Earth's core spins slower than its crust Heat exchange between the mantle and crust The convection of heat within the mantle Rotation of liquid iron in the outer core

The convection of heat within the mantle Rotation of liquid iron in the outer core

Explanation:

The electrical currents and convecting movements within the Earth's liquid core generate the planet's powerful magnetic field, which in turn drives the inner core in the way that can now be observed.

Answer C is INCORRECT. The correct answer is "Rotation of liquid iron in the outer core." For example the text from my course states that "As Earth spins on its axis, rotation of the liquid outer core generates Earth's magnetic field."
