The outer core of the Earth is made of liquid metal, and its flow both affects and is affected by our planet ' s core magnetic field. It is impossible to directly measure the outer core of the Earth, the outer boundary of which is about 2900 kilometers below our feet. However, the turbulence of the core ' s liquid is so complex—including large‐scale features and small‐scale features—that it cannot be modeled as a simulation.
