From Ripley's and verified: "If shrunk down to the size of a billiard ball, the earth would be about as smooth as one! Surface variations, such as mountains and the ocean floor, are less than 1/1000th of its diameter." Mount Everest at 8.85 km and the Marianas Trench at -11 km are inconsequential to a 12,735 km earth. #science
