The term physiography refers to physical geography: the area of ​​geography devoted to the study of the disposition of seas and lands. Geography, meanwhile, is the science that's dedicated to describe the planet Earth.

Physiography analyzes the earth's surface in a spatial and systemic way. As part of his work he investigates the links that are registered between the various surface components.

It's 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 erosion to tectonic movements.

The knowledge generated by physiography is useful for ecology, hydrology, 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's made of the forms of the earth according to lithology and relief. In this way we can talk about the physiography of a region.

A municipality, for example, can combine several physiographs. Plains, valleys and mountains, to mention a possibility, 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 physiographs it has a wide landscape variety. These conditions also usually offer many possibilities in terms of the exploitation of natural resources.
