Earth’s spin is not as steady as it looks from the ground. As ice sheets melt and aquifers are drained, scientists now say ...

Earth's axial precession is a gyroscopic wobble, analogous to a spinning top, causing its axis of rotation to trace a cone over time. The primary cause of Earth's precession is the gravitational ...

For the first time, researchers at ETH Zurich have been able to fully explain the various causes of long-term polar motion in the most comprehensive modeling to date, using AI methods. Their model and ...

The Mechanics of Earth's Spin Earth rotates once in about 24 hours with respect to the Sun, but once every 23 hours, 56 ...

When large masses of water are moved from one place to another, this changes the shape of Earth and leads to a phenomenon called true polar wander In an ideal model of our planet, the axis around ...

“Powerful” doesn’t really do the amazing (and very controversial) Three Gorges Dam justice. Since the $30 billion project was announced, Chinese officials have faced heavy scrutiny from both ...
