Scientists say shape of Earth’s inner core is changing

The Earth’s inner core is changing shape, study reveals
Scientists have discovered that the inner core's surface is changing shape, challenging previous assumptions about its solid nature
Scientists Detect Shape-Shifting Along Earth’s Solid Inner Core
The inner core is the deepest of Earth’s geological ... which “can be achieved by building seismological infrastructure in remote areas of the planet, including the ocean floor.”
Earth’s inner core isn’t just slowing, it’s also shape-shifting, study finds
The planet’s inner core was previously thought of as a hard, solid sphere. But a new study has found that its edges are softer than realized and actually changing shape.
Earth’s inner core is less solid than we thought
Earth’s core is located below the middle layer called the mantle and the outer layer –or crust. It consists of two main parts–a liquid outer core and a more solid inner core. The outer layer is made of liquid iron-nickel and is responsible for producing Earth’s magnetic field.
Scientists discover yet another change to Earth’s inner core: its shape
Scientists found that the inner core’s structure changes as it rotates. It deforms at its border, potentially accumulating more material in some areas and less in others — almost like creating hills and valleys.
Earth’s Mysterious Inner Core Is Changing Shape
Earth’s core is transforming, which could affect the length of our 24-hour day, Earth’s magnetic field, and more
