  2. Soil formation - Wikipedia

    en.wikipedia.org/wiki/Soil_formation

    The topography, or relief, is characterized by the inclination , elevation, and orientation of the terrain . Topography determines the rate of precipitation or runoff and the rate of formation or erosion of the surface soil profile. The topographical setting may either hasten or retard the work of climatic forces. [60]

  3. Orography - Wikipedia

    en.wikipedia.org/wiki/Orography

    Orography is the study of the topographic relief of mountains, [1] and can more broadly include hills, and any part of a region's elevated terrain. [2] Orography (also known as oreography, orology, or oreology) falls within the broader discipline of geomorphology. [3] The term orography comes from the Greek: όρος, hill, γράφω, to write.

  5. Stream gradient - Wikipedia

    en.wikipedia.org/wiki/Stream_gradient

    Stream gradient may change along the stream course. An average gradient can be defined, known as the relief ratio, which gives the average drop in elevation per unit length of river. [4] The calculation is the difference in elevation between the river's source and the river terminus (confluence or mouth) divided by the total length of the river ...

    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.

  7. Terrain cartography - Wikipedia

    en.wikipedia.org/wiki/Terrain_cartography

    Terrain cartography or relief mapping is the depiction of the shape of the surface of the Earth on a map, using one or more of several techniques that have been developed. Terrain or relief is an essential aspect of physical geography , and as such its portrayal presents a central problem in cartographic design , and more recently geographic ...

  8. Topographic profile - Wikipedia

    en.wikipedia.org/wiki/Topographic_profile

    A topographic profile or topographic cut or elevation profile is a representation of the relief of the terrain that is obtained by cutting transversely the lines of a topographic map. Each contour line can be defined as a closed line joining relief points at equal height above sea level. [ 1 ]
