Definition: (Geo, G. The Earth; Morph, G. Form, ology G. The science of) Geomorphology is the study of landscapes--It entails the systematic description of landforms and the analysis of the processes that create them. Geomorphologists are also concerned with understanding the function landforms and how landforms respond to changes in energy. Because landforms and landscapes result from the combined effects of lithology, structure, and process, geomorphology draws upon nearly all fields of geology. • A Landform is an individual feature, such as a slope, valley or mountain • Landscape is the he combined effect of numerous landforms, such a mountainous or desert terrain.

Use of the term geomorphic cycle will carry with.
What produces a landscape? The three independent variables that control landscape are climate (precipitation and temperature), plate tectonics, and history (time). In the long term these factors control structure, lithology, and process, the three dependent variable that landscapes reflect most closely. A common way of viewing landscape variables is outlined below as the interplay between energy, process, and resisting framework. How you approach a landscape will depend on the time frame you are considering.
Energy, process, and sediment supply are important to a geologist studying a beach. However, a geomorphologist studying the Rocky Mountains might focus on tectonic setting, climate, and process over the course of the last billion years. Roman Polanski Interviews Pdf. Energy: Energy drives geomorphic change and is the force behind process. These energy sources (listed below) drive convection in both the atmosphere and the earth, and drive chemical reactions. Without energy we would not have the hydrologic cycle, weathering, or the tectonic activity that characterize earth dynamics.
