The term physiography refers to the physical geography: the area of geography devoted to study of the disposition of the seas and lands. Geography, meanwhile, is the science that is dedicated to describe planet Earth.
Physiography analyzes the earth’s surface in a spatial and systemic way. As part of his work, he investigates the links between the various components of the surface.
It is important to highlight that these relationships give rise to different forms of land. Geoforms are a consequence of the interaction between multiple phenomena and agents that affect the physical environment, from the erosion until the tectonic movements.
The knowledge generated by physiography is useful for the ecology, the hydrology, the edaphology and other scientific disciplines. Their contributions allow to know essential characteristics for the use and management of the lands.
The notion of physiography also specifically refers to the description that is made of the forms of the earth according to lithology and the relief. In this way one can speak of the physiography of a region.
A municipality, for example, can combine several physiographies. Plains, valleys and mountainsTo mention one possibility, they are part of some areas. This means that the geography of the place includes flat lands, valleys that are surrounded by elevations and chains of mountains.
Usually when a space has different physiographies has a wide variety of landscapes. These conditions also tend to provide numerous possibilities for the exploitation of natural resources.
Physiography is related to a long list of fields of study, sciences that are dedicated to the study of a particular component of the natural space in relation to the rest. Some of the most important are the following:
* orography: the dictionary of the Royal Spanish Academy defines this term with two main meanings: the elevations that we can find in a certain area (such as a country or a region, among others) or the description that geomorphology carries out of these. The geomorphology It is the part of geology and geography that studies the surface of the earth with a morphological approach, both in the description of its forms and in the study of its origins and its behavior today;
* hydrology and hydrography: These two fields are in charge of studying continental waters, both rivers and lakes and underground water bodies. The river basins are also of interest, including their flow, its channels, its upper, middle and lower course, its hydrographic networks, its fluvial regime, its hydraulic use and its fluvial dynamics;
* glaciology: this is considered a branch of physiography. It is responsible for attending to the various phenomena of the present and the past that are linked to the Water in terms of its distribution, its extension, its features, its dynamics and all the states that it can go through in nature, from the ice sheets of the Antarctic continent and Greenland to hail and frost, without leaving out snow, ice from the rain, the sea and the lakes;
* oceanography: is dedicated to studying all aspects of the oceans, from their hydrological, biological, physical and economic features to the movements of their waters, such as currents, tides and waves. Your action on the dynamic of the atmosphere and the hydrological cycle;
* coastal geography: focuses on the relationship between the ocean, the planet and the climate. Some of the most important points are the weathering processes of things, the various kinds of waves and their impact on the beaches, both from a physical and economic point of view.
