Earth's orbit effects on climate
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.
