Scientists found that the inner core’s structure changes as it rotates. It deforms at its border, potentially accumulating ...

Researchers studying decades of earthquake data say they have found the first evidence that, in addition to spinning backward ...

The findings shed light on a deeply mysterious part of Earth that is key to life on our planet.

However, what that deformation of the inner core might look like is harder to pin down. “Maybe the topography is going up and down. Maybe it’s sloughing around like landslides,” Vidale said.

The inner core is usually thought to be shaped like a ball, but its edges may actually ... "In science, we generally try to look at things until we understand them," Prof Vidale says.

Since the waves from repeat earthquakes all start in the exact same position, if they look ... inner core to undergo 'viscous deformation', a type of change found in very thick liquids like ...
