Terrain (from Latin: terra 'earth'), alternatively relief or topographical relief, is the dimension and shape of a given surface of land. In physical geography , terrain is the lay of the land. This is usually expressed in terms of the elevation , slope , and orientation of terrain features.
A three-dimensional computer graphics representation of a geographic terrain surface created from elevation data. DEMs are the most common basis for digitally produced relief maps. dike 1. A ditch, wall, embankment, or ridge, natural or man-made, that is an obstacle to something else; another name for a levee. 2.
Limestone pavement – Natural karst landform consisting of a flat, incised surface of exposed limestone. Mesa – Elevated area of land with a flat top and sides, usually much wider than buttes. Mushroom rock – Naturally occurring rock whose shape resembles a mushroom. Natural arch – Arch-shaped natural rock formation.
A landform is a natural or anthropogenic [1][2] land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and ...
Common synonyms for geomorphometry are geomorphological analysis (after geomorphology), terrain morphometry, terrain analysis, and land surface analysis. Geomorphometrics is the discipline based on the computational measures of the geometry , topography and shape of the Earth's horizons, and their temporal change. [ 2 ]
A mobile down-warping of the Earth's crust, either elongate or basin-like, measured in scores of kilometres, which is subsiding as sedimentary and volcanic rocks accumulate to thicknesses of thousands of metres. glass. Amorphous (non-crystalline) hard and brittle solid such as soda-lime glass. glauconite.
Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the land forms and features themselves, or a description or depiction in maps. Topography is a field of geoscience and planetary science and is concerned with local detail in general, including not only relief, but also natural, artificial ...
In physical geography and physical geology, aspect (also known as exposure) [1] is the compass direction or azimuth that a terrain surface faces. [2] For example, a slope landform on the eastern edge of the Rockies toward the Great Plains is described as having an easterly aspect. A slope which falls down to a deep valley on its western side ...
