What is the primary mountain range in South America?

The primary mountain range in South America is the Andes Mountains. Spanning over 4,300 miles along the western edge of the continent, the Andes is not only the longest mountain range in South America but also one of the longest in the world. It stretches through seven countries, including Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. The Andes are known for their diverse ecosystems, reaching high altitudes and influencing the climate and geography of the surrounding areas.

In contrast, the Rocky Mountains are primarily located in North America, extending from Canada into the United States. The Appalachian Mountains are also situated in the eastern United States and do not extend into South America. The Himalayas are situated in Asia, primarily forming the northern borders of India, Nepal, and Bhutan, making them geographically irrelevant to the question about South America. Thus, the Andes stand out as the defining mountain range of the continent.
