Physical geography is one focused on studying the configuration of the land spaces and seas.

Also called physiography, physical geography specializes in natural geographic space, considering the Earth's surface as a whole. His knowledge is complemented by those contributed by human geography (which studies the link between human communities and the environment in which they reside).

Physical geography seeks to contribute to the understanding of the processes and geographic patterns that occur in the natural environment. The oceanography, the topography, the glaciology and hydrography are some of the fields of study of this geographical subdiscipline. To develop his studies, he uses other sciences, such as physics and geology.

Next we will see the fields of study mentioned above in greater detail. The oceanography, for example, is nothing but the study of the seas and oceans, with a focus on their physical, hydrological, economic and biological features. This science is also interested in tides, ocean currents and waves, among other movements of ocean waters. Another of the main aspects of oceanography is the way in which the seas and oceans influence the hydrological cycle and atmospheric dynamics, which supposes the fundamentals of meteorology and, indirectly, of climatology.

The orography, moreover, defined as elevations found in a given area, as well as the description of these from the field of geomorphology. Specialists in this field define the lower limit of the parts of the Earth where the ocean doesn't reach. The fidelity to the reality of the representation of the lands depends directly on the resolution used when dividing them into cells.

With regard to glaciology, he contributes to physical geography with his study of solid-state water: polar ice caps, glaciers, ice shelves and icebergs are some of the most common examples. The phenomena that this discipline attends belong to both the present and the past, and cover both its development and its causes, its distribution and its extension.

The hydrography is easily unlike glaciology in serving water in a liquid state, and this includes lakes, rivers and groundwater, as well as their characteristics and properties.

It's important to keep in mind that physical geography studies biophysical issues and the link between them and the actions of human beings. That's why he works with the natural phenomena that occur on Earth and with the interactions that man maintains with the environment, always starting from a spatial perspective.

Although it can develop historical studies (for example, analyzing how the landscape changes over thousands of years), it also has the power to focus on the present (by detecting and measuring changes in land use, to cite a possibility).

The main applications of physical geography take place through the materials that compose it and can take many forms, depending on the characteristics and needs of each area. Its origins date from the third century BC. C., although its evolution had a large number of milestones throughout these two millennia.
