WebAs the Earth rotates, it behaves rather like a gyroscope. When a gyroscope spins in the Earth's gravitational field, its rotation axis slowly turns due to an effect called precession. Likewise, the Earth is subjected to the Sun's gravitational field as it rotates, and this causes its rotation axis to precess. 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 "polar motion." Measurements for the 20 th century show that the spin axis drifted about 4 inches (10 centimeters) per year.
