The Amazon River is the second longest river in the world and forms part of the border between Brazil and its neighboring countries of Peru and Colombia. At over 4,000 miles long, it carries more water than any other river and flows through major South American cities like Belem, known for its Goeldi Museum displaying Amazon Basin culture and wildlife. Various languages like Spanish, German and Portuguese are spoken among cities along the Amazon River, which also passes through settlements of indigenous tribes.
