Geomorphology

the definition of Geomorphology

In essence geomorphology can be defined as the science of the earth, and their romance aspects that influence it. Said Geomorphology (geomorphology) derived Greek, which consists of three words, namely: Geos (er at h / earth), m or ph os (shape / form),

logos (knowledge or science). Based on these words, the notion

geomorphology is the knowledge of the forms of the earth's surface.

Worcester (1939) defines geomorphology as a description and interpretation of the novel form earth. Worcester definition is broader than just knowledge about landscape (the science of landforms), for including a discussion of the events of the earth in general, such as the formation of ocean basins (ocean basin) and continental shelf (continental platform), and the forms of the structure more smaller than that mentioned above, such as plain, plateau, mountain and so on.

Lobeck (1939) in his book "geomorphology: An Introduction to the study of landscapes".

Landscapes is meant here is landscape natural (natural landscapes). In describe and interpret forms landscape (landform or landscapes) there are three factors to consider in the study of geomorphology, namely: structure, proces and stadia. The third factor is a unity in the study of geomorphology.

The expert Geomorphology study landscape sees forms and find out why a landscape occur, In addition, to know the history and development of a landscape, in addition to predicting changes in the changes that may occur in the future through a combination of field observations, experiments physical and numerical modeling . Geomorphology is closely related to the fields of science such as physiography, meteorology, climatology, hydrology, geology, and geography.

The study of the geomorphology of the first time that a study done for pedology, one of the two branches of soil science. Landscape is a response to a combination of natural and anthropogenic processes. Landscape formed by tectonic uplift and volcanic activity, while denudation occurs through erosion and mass wasting. The results of the process of denudation is known as a source of sediment were then transported and deposited on land, beach and sea. Landscape can also decreased by subsidence events caused by tectonic processes or as a result of physical changes that occur under sediments. Processes are one and the other occurred and is influenced by differences in climate, ecology, and human activities.

Geomorphic models are first introduced is a model of geomorphic cycle or

erosion cycle, developed by William Morris Davis (1884-1899). Geomorphic cycle is inspired of the theory of uniformitarianism first introduced by James Hutton (1726-1797). In connection with the forms of the valley contained on earth, geomorphic cycle is able to explain the sequence of an eroding river valley resulting in the depths of a valley becomes deeper, while the process of erosion that occurs on both sides of the valley that occur regularly will make the valley be gentle back and elevation becoming increasingly more anyway. This cycle will work again in case of removal from the mainland.
