Ecuador
Ecuador's capital is Quito, which is in the province of Pichincha in the Sierra region. Its largest city is Guayaquil, in the Guayas Province. Cotopaxi, just south of Quito, is one of the world's highest active volcanoes. The top of Mount Chimborazo (6,268 m, or 20,560 ft, above sea level), Ecuador's tallest mountain, is the most distant point from the center of the Earth on the Earth's surface because of the ellipsoid shape of the planet.
