Researchers found evidence that the Earth's inner core is changing shape, suggesting unseen processes affecting its movement over time.

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 of course cannot cut into Earth and directly observe its insides. Instead, their knowledge is inferred from the vibrations generated by earthquakes that pass through the planet. The speed and the direction of the seismic vibrations change depending on the density and the elasticity of the rocks.

Earth’s core is transforming, which could affect the length of our 24-hour day, Earth’s magnetic field, and more

Changes to the inner core has long been a topic of debate for scientists. The post Study claims Earth’s inner core less solid than previously thought appeared first on Talker.

Scientists have for some time suspected climate change is affecting Earth's beating heart. Now, a study offers specifics on changes at the planet's unreachable inner core. Building on 2024 research that described how the solid ball of iron and nickel at the center of the Earth,
