Earth, inner core

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.
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 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.
