Abstract

The present work has as central discussion to approach the urban geomorphology, as well as the implications resulting from the interrelation man, relief, occupation and consequently the impacts caused in the environment, thus the proposed work aims to characterize the process of urban expansion of the city. nucleus Cidade Nova - Marabá / PA, from 1990 to 2019, through geomorphological analysis, showing the relief modifications and the environmental impacts generated by the urbanization activity.
