12-year-old Sathwik Karnik of Massachusetts wins National Geographic Bee

Twelve-year-old Sathwik Karnik of Norfolk, Mass., has won the 2013 National Geographic Bee.

Sathwik correctly named Chimborazo as the mountain in Ecuador that represents the farthest point from the Earth's center to clinch the title. Thirteen-year-old Conrad Oberhaus of Lincolnshire, Ill., finished second.

Sathwik led throughout the final round of the 25th annual geography bee and was the last contestant to get a question wrong. He wins a $25,000 scholarship, a trip to the Galapagos Islands and a lifetime membership in the National Geographic Society.

Sathwik's older brother made the finals in 2011 and 2012, finishing 5th and 6th.
