Answer the following question.
What could be the reasons behind the formation of swamps in the extensive continental location of Pantanal ?
Pantanal is one of the largest wetlands in the world, lying towards the southwest part of the highland areas. It is a region of swamps and marshes in northwestern Mato Grosso do Sul in Brazil and, extending into Argentina too. It is a very precious resource of Brazil, home to an array of plant- and animal species.
Water from the Planalto highlands flows into the gradually-sloped, large depression of Pantanal. From there, the water flows out as the Paraguay River and its tributaries. The Pantanal forms a vast swampy area as a result of deposits from the several rivers and water systems flowing into it.
