South American Lakes Quiz – Mirrors of the Andes

South America's lakes range from high Andean waters to vast coastal lagoons. Lake Titicaca sits at about 3,812 meters, while Patagonian lakes glow turquoise from glacial silt and coastal lagoons support rice farms and bird life.

Lakes are central to culture. The Uros live on reed islands on Titicaca, the Inca believed their ancestors rose from its waters and lakeside towns in Chile and Argentina reflect German and Swiss settlers who arrived in the 1800s.

Lakes also show natural wonders, from Maracaibo's nightly lightning to the Marble Caves and red flamingo lagoons. Protecting them from pollution and mining remains a challenge for the region.
