Physical Division of Brazil> Islands

Brazilian Island:

• Brazil also includes some islands in addition to the mainland.
• They can be divided into two types: Coastal islands and Marine islands.
• The majority of the coastal islands were formed as a result of deposition.
• The mainland included marine islands.
• They are over 300 kilometers away from the Atlantic Ocean's mainland.
• These are mostly rocky islands that form the tops of submerged mountains.
• The islands near the coast of the South Atlantic Ocean are coral islands and they are called atolls.

Physiography of Brazil 

• Even a casual look at the map reveals that highlands, plateaus, and small mountains cover a large portion of Brazil.
• There are no extremely high or long-reaching mountains in the country.
• With the exception of the northern Amazon basin, as well as the southwest along the upper parts of the Paraguay basin, there are no wide plains in the country. Even the coastal plains are limited in their expanse. Brazil's physiographic divisions are as follows. 

1. The Highlands 
2. The Great Escarpment 
3. The Coastal region  
4. The Plains 
5. The Island groups

• Brazil has both coastal islands and marine islands apart from its mainland.
• Coastal islands are formed mainly by deposition near the shore.
• Marine islands lie over 300 km from the mainland in the Atlantic Ocean.
• These marine islands are usually rocky and are the tops of submerged mountains.
• Some islands in the South Atlantic Ocean are coral islands and are known as atolls.
