Question

What could be the reasons behind the formation of swamps in the extensive continental location of Pantanal?

Answer 1

Pantanal which lies towards the southwest part of the highland areas is one of the largest wetlands in the world. The reasons behind the formation of swamps in the extensive continental location of Pantanal are as follows:

1. Pantanal is surrounded by Paraguay and its tributaries. These rivers collect its headwaters from the southern portion of the Highlands.
2. When the river is flooding, a large amount of sediment comes out with the flow. Heavy sediments are found towards the bottom of the river while suspended particles are scattered all over.
3. It means that Pantanal is formed due to the work of the river Paraguay and its tributaries. Due to this continuous process, Pantanal has developed into marshy land.
4. Paraguay river is located in the south-western part of Brazil and flows towards Argentina.
5. Thus, Pantanal is formed due to the Paraguay river and it is a region of swamps and marshes in north western Mato Grosso do Sul in Brazil which extends into Argentina too.

Answer 2

1. Pantanal is one of the largest wetlands in the world, lying in the south west part of the highland areas.
2. It is a region of swamps and marshes in northwestern part of Mato Grosso do Sul in Brazil and it extends into Argentina too.
3. This region is drained by the river Paraguay and its tributaries.
4. They collect the water from the highland areas and deposit the sediments in the low-lying Pantanal region.
5. Pantanal is a gently sloped basin which is submerged throughout the year due to the filling of the sediments and water in the depression area of the Pantanal.
