(National Geographic) Australia is not quite where you think it is. The continent has shifted by 4.9 feet since the last adjustment was made to GPS coordinates in 1994, reports the New York Times.
All of the Earth’s continents float on tectonic plates, which glide slowly over a plastic-like layer of the upper mantle. And the plate that Australia sits on has been moving relatively fast, about 2.7 inches a year (northward and with a slight clockwise rotation).
In contrast, the North American plate has been moving roughly one inch a year, though the Pacific plate moves three to four inches a year.
