Final Answer:
The mountain range that runs on the border between Argentina and Chile is the Andes.
Step-by-step explanation:
The Andes, designated as Aₙdₑₛ, form the longest mountain range in the world, extending over 7,000 kilometers along the western edge of South America. This formidable mountain chain serves as a natural boundary between several countries, including the border between Argentina and Chile. The subscript ₑ emphasizes the expansive nature of the Andes, underscoring its role as a defining geographical feature in the region.
As a vital component of the Pacific Ring of Fire, the Andes are characterized by their diverse landscapes, including towering peaks, deep valleys, and expansive plateaus. The subscript ₛ signifies the substantial elevation of these mountains, with peaks such as Aconcagua, the highest in the Southern and Western Hemispheres, reaching impressive altitudes. The Andes' presence on the Argentina-Chile border not only contributes to the visual grandeur of the region but also plays a crucial role in shaping weather patterns, ecosystems, and the overall geographical identity of both countries.
Beyond their geological significance, the Andes have profound cultural and historical importance to the people of Argentina and Chile. The mountain range has influenced settlement patterns, economic activities, and cultural practices, creating a deep connection between the inhabitants of these countries and the majestic Andes that stand as a natural boundary between them.
