Unveiling the Intricate Texture of Earth's Inner Core

Seismic waves passing through the Earth's inner core have revealed that it is textured rather than homogenous. This discovery provides valuable insights into the age, composition, and structure of the inner core, which plays a crucial role in maintaining the planet's geomagnetic field. By analyzing echoes of powerful earthquakes, researchers have found that the inner core exhibits inhomogeneity on a scale of "grains" smaller than 10 kilometers. The texture becomes stronger towards the center of the Earth, suggesting rapid growth during its formation. The study sheds light on the complex nature of Earth's inner core and its significance in understanding the planet's dynamics.
