The relief of Brazil has old formation and currently there are several classifications for it. These include the following teachers:
- Aroldo de Azevedo - This classification dates from 1940, being the most traditional. It mainly considers the altimeter level to determine what a plateau or a plain is.
- Aziz Nacib Ab'Saber - Created in 1958, this classification despises the altimetric level, prioritizing the geomorphological processes, that is, erosion and sedimentation. Thus, the professor considers plateau as a surface on which the process of wear predominates, while plain is considered a sedimentation area.
- Jurandyr Ross - is the most recent classification, created in 1995. It is based on the Radambrasil project, a survey made between 1970 and 1985, where aerial photos were taken of the surface of the Brazilian territory, using a sophisticated radar. Jurandyr also uses geomorphological processes to elaborate his classification, highlighting three main forms of relief:
According to this classification, Highland It is an irregular surface, with altitude above 300 meters and erosion product. Flat land It is a flat area formed by the recent accumulation of sediment.
Lastly, depression It is a surface between 100 and 500 meters in altitude, with gentle slope, flatter than the plateau and formed by erosion process. The following figure shows this representation of the Brazilian relief.
