WebSep 19, 2024 · Earth is not a perfect sphere. When it rotates on its spin axis -- an imaginary line that passes through the North and South Poles -- it drifts and wobbles. These spin-axis movements are scientifically referred to as … WebApr 24, 2024 · The Earth spins around an axis kind of like a top, explains Vincent Humphrey, a climate scientist at the University of Zurich who was not involved in this research. If the weight of a top is moved around, the spinning top would start to lean and wobble as its rotational axis changes.

WebGyroscopic (spin) Drift First, a quick fact about spinning objects… Picture a spinning object like a bullet or a top. The spinning thing has a ‘spin axis’, about which it’s spinning. If you try to disturb the spin axis by applying a force, or a torque to that axis, the spinning object reacts in a strange way. Rather than simply WebAug 6, 2024 · Earth does not always spin on an axis running through its poles. Instead, it wobbles irregularly over time, drifting toward North America throughout most of the 20th Century (green arrow). That direction has changed drastically due to changes in water mass on Earth. Credits: NASA/JPL-Caltech
