Let's follow up on the asteroid impact problem. The probability that an asteroid impact would strike Columbia University is very small, but what about striking land anywhere on Earth? Will most asteroids fall on land, or in the ocean? The total surface area of the landmass on Earth is 1.49 x 108 kmz. The radius of the Earth is 6.37 x 106 m.
