For a while, core and the Earth's rotation matched. Later, the rotation speed of the Earth's core reduced even more until it started moving in reverse direction.

The rotation of the Earth's inner core may be reversing, scientists have found in a study that sheds new light on geological processes occurring deep within our planet.

Inside of the Earth, the inner core is also spinning in the same direction, but that spin might slow down or speed up every once in a while. If it slows down to slower than the Earth’s rotation ...

The study's authors, Xiaodong Song and Yi Yang of China's Peking University, said they found that the inner core's rotation "came to near halt around 2009 and then turned in an opposite direction." ...

A study suggests the Earth’s inner core, which rotates independently from Earth’s surface, slowed down — but it didn’t stop or reverse direction.

For billions of years, Earth has rotated in the same direction as the sun — but what if that direction were reversed? Deserts would cover North America, arid sand dunes would replace expanses of ...

The Earth is always rotating. Despite some hair-brained theories that the Earth is flat, all you need to see evidence of the Earth’s rotation and its roundness is to set up a camera and record ...

Likewise, the rotation of the earth gives rise to an effect that tends to accelerate draining water in a clockwise direction in the Northern hemisphere and counterclockwise in the Southern." On ...
