Another point of attention is the meeting of coastal tablelands with the sea, originating cliffs (Fig. 5.9). They have sedimentary origin and include erosion scarps of
the Coastal Boards caused by marine abrasion. It is a beautiful landscape with tourist appeal and still suffering the erosive action of waves.
5.2.3 The South Coast Coastal Tropical in Brazil
And lastly, the south coast begins at the Cabo de São Tomé, in Rio de Janeiro, and
extends to the Arroio do Chuí, Rio Grande do Sul (Fig. 5.10). In this section, we find
tropical wetlands with rugged coastline with rocky shores and crystal cliffs, where
the ancient folds are very close to the sea (Fig. 5.11). The coastal plain tends to be
small and discontinuous, with the common creation of Baixada Fluminense and
Santista, as well as the coastal lagoons.
In this last section, wetlands are associated with estuarine-lagoon systems, a
wide variety of macrophyte plant communities that vary according to the water
regime, morphometry and other physical characteristics of each system (Schwarzbold
and Schäfer 1984).
