• It has undergone significant expansion in recent years, with the construction of a new set of locks that can accommodate larger vessels, known as Neopanamax ships.

Andes Mountains

• The Andes Mountains serve as the western boundary of South America, stretching from Colombia down to Chile and Argentina.

• As the longest mountain range in the world, the Andes play a significant role in shaping the continent's physical geography.

• They form natural barriers, dividing the continent into distinct regions and affecting the movement of air masses, creating diverse climate zones.

• The Andes are home to unique ecosystems and biodiversity, including high-altitude grasslands, cloud forests, and alpine environments.

• They also hold valuable mineral resources and have influenced human settlement and cultural development throughout history.

Amazon Basin

• The Amazon Basin marks the northern boundary of South America, covering a vast area of tropical rainforest and river systems.

• The Amazon River, the largest river by volume in the world, flows through this region and plays a crucial role in the continent's hydrology.

• The Amazon Basin is renowned for its incredible biodiversity, hosting countless species of plants, animals, and microorganisms.

• It is home to indigenous communities that have depended on the forest for sustenance, cultural practices, and medicinal knowledge for centuries.

• The Amazon Basin also acts as a significant carbon sink, absorbing and storing vast amounts of carbon dioxide, contributing to global climate regulation.

Paraguay River

• The Paraguay River is a major waterway in South America, flowing through Brazil, Paraguay, and Argentina.

• It stretches approximately 2,550 kilometres (1,580 miles) in length, making it one of the region's longest rivers.

• The river serves as a natural boundary between Paraguay and Brazil, and Paraguay and Argentina.

• It plays a crucial role in the transportation of goods, facilitating trade between landlocked Paraguay and its neighbouring countries.

• The Paraguay River basin is home to diverse wildlife and ecosystems, including the Pantanal wetlands, which are renowned for their biodiversity.

• The river is also a popular destination for recreational activities such as boating, fishing, and wildlife watching.

• The Itaipu Dam, located on the Paraguay River between Brazil and Paraguay, is one of the world's largest hydroelectric power plants.

Uruguay River

• The Uruguay River forms part of the boundary between Argentina and Uruguay.

• It originates in Brazil and flows for approximately 1,600 kilometers (990 miles) before reaching the Atlantic Ocean.

• The river is an important transportation route, facilitating trade and commerce between Argentina and Uruguay.

• It is also a significant source of hydroelectric power, with several dams constructed along its course.

• The Uruguay River basin supports various ecosystems, including wetlands, forests, and grasslands, providing habitats for numerous species.

• Recreational activities such as boating, fishing, and water sports are popular along the river.

Rio de la Plata

• The Rio de la Plata is a large estuary located between Argentina and Uruguay, formed by the confluence of the Uruguay and Paraná rivers.

• It is one of the widest estuaries in the world, spanning approximately 220 kilometres (137 miles) at its widest point.

• The river serves as a natural border between Argentina and Uruguay, and its basin covers a significant portion of both countries.

• The Rio de la Plata is an important shipping route, facilitating trade and maritime transportation.

• It also supports a rich marine ecosystem and is a vital fishing ground for various species.

• The river estuary is a popular tourist destination, offering scenic views, waterfront promenades, and recreational activities.

Cape Horn

• Cape Horn is a rocky headland located on Hornos Island in southern Chile.

• It is the southernmost point of South America and marks the northern boundary of the Drake Passage.
