Q: What's the driest place on Earth?
A: That would have to be in the country of Chile, said Brent McRoberts of Texas A&M University. "A small town called Arica in Chile has gone as long as 14 years without any measurable rain," McRoberts reported. "There was a 59-year period there when it averaged only three-tenths of an inch of rain. No place in the United States comes close to being that dry."
