The planet is made up of an infinite number of ecosystems, each of which has its own landscape, particularities and characteristics.
Ecosystems are formed from the interaction between different elements, such as water, temperature, sun, soil, air, among others. As these elements differentiate, the landscape configurations change.
The state of Tocantins has a great natural variety, which is demonstrated from the main components of landscape formation, therefore, the most prominent are: relief, climate, vegetation and hydrography.
In Tocantins there are basically three types of relief: plateau, plains and depressions. As for the altitude, most of the territory does not exceed 500 meters above sea level.
The plateaus are found in areas close to Araguaia-Tocantins, located in the south of the state, in this region the altitudes range from 300 to 600 meters. The highest point in Tocantins is located in Serra das Traíras, with 1,340 meters of altitude.
In Tocantins, the prevailing climate is tropical, which has two well-defined seasons, one dry and one rainy, the first producing an annual average temperature of 26ºC and the second 32ºC. The pluviometric indexes during the year are of 1800 mm in the north and in the east, in the south of the state the index decreases to 1000 mm.
The vegetation cover of the State is composed of 90% of cerrado, this type of vegetation has low trees with deep roots, trunks twisted and thick leaves and bark, the territory is a transition area between cerrado and the Amazon Forest, this one presents itself to the north of the State.
The state is part of the main water potential in Brazil, thus the territory shows important rivers such as the Araguaia, Tocantins, Sono, Balsas and Paraná, the largest river island in the world, called Ilha do Bananal.
