  1. A typical desk globe is designed to be a geometric sphere and to rotate smoothly when you spin it.
  2. Our actual planet is far less perfect -- in both shape and in rotation.
  3. Earth is not a perfect sphere. When it rotates on its spin axis
  4. -- an imaginary line that passes through the North and South Poles
  5. -- it drifts and wobbles.
  6. These spin-axis movements are scientifically referred to as "polar motion.
  7. " Measurements for the 20th century show that the spin axis drifted about 4 inches (10 centimeters) per year.
  8. Over the course of a century, that becomes more than 11 yards (10 meters).
  9. Using observational and model-based data spanning the entire 20th century,
  10. NASA scientists have for the first time identified three broadly-categorized processes responsible for this drift
  11. -- contemporary mass loss primarily in Greenland, glacial rebound, and mantle convection.
