Há dois períodos evidentes que caracterizam o alagamento periódico no Pantanal. O das cheias e a dos vazantes. Explique cada um deles.

The Pantanal is an area in the northern part of Argentina, and part of Brazil in the area of the borderline with Argentina. This area has two seasons, one is the wet season, and the other one is the dry season.

The wet season is characterized by heavy rainfall for a prolonged period of time, and in that period, the whole area becomes a vast marshland.

The dry season is characterized by warm and dry weather, and there is no precipitation for months, so in this period the Pantanal dries out, and the marshland is looking more like a vast grassland with little ''islands'' of trees and shrubs.

Most of the animals living here are adapted very well for both, life in the water, and life on land.
