This paper evaluates the role of geographical scales in assessing this diversity-stability relationship among counties, states, Economic Areas (EAs), metropolitan counties and metropolitan statistical areas (MSAs) in the contiguous U.S. When choosing geograph...
متن کاملNeotectonic features of Gotvand - Lali region, southwest Iran
The morphology of the Earth is a result of interactions between climate, tectonics, and geology and the investigation of neotectonics is one of the vital disciplines in Earth science, because the results of regional studies of active tectonics are significant for evaluating natural hazards as well as land use development and management in populated areas. In this regard neotectonic features of ...
