3-D South America
This image is a portrait of a 3-D elevation model of South American continent derived from topographic data. The rather thin, green strip at the base (left side) of the massive, white Andean Cordillera, represents the coastal environments. The Atacama and Peruvian deserts occupy the upper half of the image. The now submerged, continental margin is represented by the tan, orange and yellow parallel strips, bordered by the plunging, blue abyss of the Pacific Ocean.
