LANDSCAPE PHYSIOLOGY AND ITS IMPLICATIONS IN THE GEOMORPHOLOGY OF INDIGENOUS LAND RAPOSA SERRA DO SOL - UIRAMUTÃ/RORAIMA/BRAZIL

Abstract

ABSTRACT: The geomorphological landscape of the state of Roraima is formed by the presence of reliefs whose altitudes vary between 80 and 2,800 meters, which constitutes a diversified and exuberant scenery. In this sense, this article aims to demonstrate the landscape physiography and its influence on the geomorphology of the northern part of the municipality of Uiramutã / Roraima / Brazil, covering the region of the Raposa Serra do Sol Indigenous Land. The methodology used involved overflight in the region, collection and soil analysis of the Ingarikó region. The results demonstrate that the geomorphology of the area is mainly due to the intense periods of climatic fluctuation in the region, being represented by the Roraima Sedimentary Plateau, which is formed by the presence of several forms of relief, such as tables, testimonial hills, slopes, hills and hills ravines with the presence of suspended valleys, numerous grooves and ravines that evolve into gullies, as well as trapezoidal and triangular facets that reflect the relief dynamics in a frank dissection process, which reflect in acidic soils and low fertility content.
