Earth's magnetic poles are close to its geographic poles due to fluid dynamics within the planet's outer core
the verdict
SUPPORTED
the evidence backs this
confidence 80/100
Earth's magnetic poles remain closely aligned with its geographic poles due to fluid dynamics and magnetohydrodynamic processes occurring within the planet's outer core and interior.
