The inner, solid part of Earth's core behaves like a spinning top; it rotates around its axis along with the entire environment and makes cyclical movements. This occurs with regularity every 8.5 ...

The study, published in March in the journal Geophysical Research Letters, says the dramatic ice melt would redistribute the ...

This precession is caused by the pull of the sun and the moon acting on the slightly nonspherical shape of the earth. Superimposed is a subtler wobble. The axis keeps steady in space, but over an ...

First of all the rotation axis changes relative to the Earth’s surface which is referred to as polar motion. The main component of polar motion is the so-called Chandler wobble. Although it was ...

Apparently, it’s moving further away from the Earth each year. At an annual rate of 3.82 centimeters, the moon's creeping ...

Ocean circulation and pressure on the seabed that pulls on the Earth’s axis. The “Chandler Wobble” – a natural shifting of the Earth’s axis as the planet is not perfectly spherical ...

Following is a transcript of the video. Early in the history of our solar system, something mysteriously knocked Earth slightly off its axis. So today we tilt at 23.5 degrees. But what would ...

As climate change melts ice sheets and glaciers, water is being redistributed across the globe — and could end up moving the ...

As ice sheets melt and ocean mass gets redistributed around the planet, Earth's geographic North and South poles could shift up to 89 feet (27 meters) by 2100 as the planet's axis of rotation ...

including a 100,000 year cycle in the shape of the orbit (eccentricity), a 41,000 year cycle in the tilt of the Earth's axis (obliquity) and a 20,000-year cycle in the "wobble" — much like a top ...
