An Eco-sustainable World
Nature to be saved



The Paranà is a river in South America that flows through Brazil, Paraguay and Argentina. This river is 4,880 kilometers long and is considered the second longest river in South America after the Amazon River.

Etymology –
The name “Paraná” comes from the Guaraní language, spoken by several indigenous groups in South America, especially in Paraguay, Argentina and parts of Brazil. In Guaraní, “para” means “sea” or “river” and “ná” means “similar to” or “similar to”. Therefore, the term “Paraná” can be roughly translated as “sea-like river” or “great river” in reference to its width and the importance of this river in the region.

Geographical Features –
The Paraná is a river located in South America, which flows through several countries, including Brazil, Paraguay and Argentina.
The Paraná is one of the longest rivers in the world, with a length of approximately 4,880 kilometers. It originates in Brazil and flows through Paraguay and Argentina before flowing into the Atlantic Ocean.
