Brazil has a coastline of about 7400 km. They are divided into two parts namely northern coast and the eastern coast . The northern coast extends from Amapa province in the north to Rio Grande Do Norte in the east. This coast can be called as North Atlantic Coast. From here, the eastern coast extends towards the south.
The northern coast is characterized by mouths of many rivers including the Amazon. Therefore, this region is a low-lying region.
On this coast lie the Marajo island, Marajo and Sao Marcos Bays.
Marajo, a large coastal island located between River Amazon and River Tocantins, lies on the northern coast.
The eastern coast receives a large number of smaller rivers. The only major river which meets the Atlantic Ocean here is Sao Francisco.
The Brazilian Coast is characterized by a large number of beaches and sand dune complexes.
The Brazilian Coast is protected in some areas by coral reefs and atoll islands.
