: A 2025 study from USC found that the surface of the inner core is changing and may be "softer" than previously thought.
: The "softness" of the solid core is attributed to hyperactive iron atoms that move within their molecular structure more than expected. Comparison of Earth's Core Layers Corre!
: Scientists now believe the inner core can behave like a shape-shifting material that deforms over human timescales due to interactions with the liquid outer core. : A 2025 study from USC found that
