Where are the Andes Mountains uplifted by ongoing plate collision?
Quick Answer
The Andes run along the western edge of South America, from Venezuela to southern Chile and Argentina. They formed mainly from the subduction of the Nazca Plate beneath the South American Plate.
The Full Story
The Andes are the longest continental mountain chain in the world, stretching about 7,000 kilometers along South America’s Pacific margin. Their uplift is driven by an active convergent boundary where oceanic crust of the Nazca Plate is forced beneath the South American Plate. This process produces earthquakes, volcanoes, and rapid uplift across much of the range. The Andes are still geologically active, making them a classic example of mountain building in progress.
