There are no west-flowing rivers in Brazil.

Question

Q.5 (4) There are no west-flowing rivers in Brazil.

Doubtly AI · Accepted Answer

Answer: Because there is no land sloping towards the west in Brazil; the Andes lie to the west (outside Brazil) and the highlands lie in the east. The Amazon rises in the Andes, west of Brazil, and flows eastwards across the lowland into the Atlantic Ocean. Its tributaries from the Brazilian Highlands flow northwards, and those from the Guiana Highlands flow southwards, to join the Amazon; so they too drain to the east. The Brazilian Highlands and the Great Escarpment lie in the east; rivers rising on them flow either eastwards into the Atlantic (e.g. Sao Francisco, after flowing north) or southwards (Parana, Paraguay, Uruguay). Since the western part of Brazil is the low Amazon basin and not a coast or a westward slope, no river flows towards the west.

Even a cursory look at the map will make one realise that there is North Atlantic and South Atlantic Ocean to the northern and eastern coasts of Brazil respectively. The southern Brazil is occupied by an extensive plateau. The height (altitude) decreases gradually to its north. A number of rivers take off from the terminal portion of the highlands and flow northwards to meet Atlantic Ocean. The only major river Sao Francisco flows towards the north for a distance and then takes a sharp eastward turn to enter the coastal strip along the Atlantic Ocean. Moreover, Amazon which is the longest river in Brazil, originates from the eastern slopes of Andes Mountains in Peru, flows eastward and meet North Atlantic ocean. Likewise, Parana, Paraguay and Uruguay originate from southern slopes of the Highlands and flows through the south-western part of Brazil. Therefore, there are no west-flowing rivers in Brazil.
