Scientists have found evidence that the inner core of the Earth may have changed shape by over 100m in the past 20 years, potentially due to interactions with the outer core. This could impact Earth's magnetic field and overall planet dynamics.
Key Points
Inner core of Earth may have deformed by 100m or more in the past 20 years
Changes in shape potentially caused by interactions at the inner and outer core boundary
Understanding Earth's core is crucial for studying the magnetic field and planet's stability
Pros
Provides insight into the dynamics of Earth's core and its impact on the planet
Could lead to a better understanding of Earth's magnetic field
Cons
Uncertainties and limitations in interpreting the data
