The longest continuous mountain range on Earth is the Andes, which stretches along the western edge of South America. Spanning approximately 4,300 miles (7,000 kilometers), the Andes run through seven countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina.
The Andes are not only impressive in terms of their length but also in their diverse ecosystems and varying elevations. The range features an array of climates, from tropical in the north to alpine in the south, and is home to unique wildlife and indigenous cultures.
Aside from the Andes, another significant continuous mountain range is the Rocky Mountains in North America, which extend about 3,000 miles (4,800 kilometers) from Canada through the United States to New Mexico. While they are shorter than the Andes, the Rockies are an iconic range with stunning landscapes and geological features.
