Final answer:
The archipelago at the southern tip of South America divided between Chile and Argentina is known as Tierra del Fuego. It is characterized by tundra-like conditions and is part of the European Commercial Region in the Southern Cone, with a population largely of European descent.
Step-by-step explanation:
The archipelago located at the southern tip of South America that is divided between Chile and Argentina is known as Tierra del Fuego. This region is characterized by tundra-like conditions and treeless plains, reflecting a dramatic shift in climate as one travels south through the Southern Cone of South America. Notable features of Tierra del Fuego include the Southern Andes and a portion of the region that is considered part of Patagonia.
Tierra del Fuego forms the southernmost extremity of the American landmass and is split by an international border between Chile and Argentina. This unique geographical location, combined with its rugged terrain and sparse population, make it a region of considerable interest for both nations. The Southern Cone itself is also noteworthy for its European Commercial Region, largely composed of people of European descent who have created some of the most developed economies in South America.
Temperatures in Tierra del Fuego become cooler toward the south, with an environment that holds significant natural resources and has traditionally supported livelihoods such as livestock raising, amidst its semiarid Patagonian landscapes.
