1. Geographical factors: Geographically, Chile is located on the southern coast of South America, bordering the tall and continuous Andes in the east and the Pacific Ocean in the west. This is the existence of the Andes. Chile is cut off by mountains, losing the condition of extending eastward, and can only develop in the north-south direction, which is also an important reason for the gradual formation of a narrow situation between the north and the south.
2. Historical factors: From the perspective of historical development, the reason why Chile formed a long and narrow territory has a lot to do with their lack of communication and their lack of sense of identity in the surrounding areas. After all, there is not much communication between Chile and Argentina in the east of the mountain range, and Bolivia in the north is even more difficult to contact, so Chile has almost no sense of identity with the surrounding areas, and this situation has formed over time.
3. Traffic factors: The coastal areas of Chile are plains, so almost all the traffic in Chile is built along the coastline. Since the north-south traffic is convenient, there are naturally many people coming and going. On the other hand, the east-west direction has not developed due to geographical reasons, and the traffic is blocked, which can even be said to be isolated from the world.
