Scientists who just months ago confirmed that Earth’s inner core recently reversed its spin have a new revelation about our planet’s deepest secrets.
They identified changes to the inner core’s shape.
Earth’s innermost layer is a hot, solid ball of metal surrounded by a liquid metal outer core.
For decades, planetary scientists suspected that the solid inner core deformed over time as it spun.
Now, researchers have found the first evidence of changes taking place over the past 20 years in the shape of the inner core.
Signs of the core’s deformation appeared in waves from earthquakes that were strong enough to reach Earth’s center.
