  2. Graded bedding - Wikipedia

    en.wikipedia.org/wiki/Graded_bedding

    Graded bedding is a sorting of particles according to clast size and shape on a lithified horizontal plane. The term is an explanation as to how a geologic profile was formed.

  3. Cuesta - Wikipedia

    en.wikipedia.org/wiki/Cuesta

    These landforms differ only on the steepness of their backslopes and the relative differences in the inclination of their backslopes and frontslopes. These differences depend upon whether the dip of the strata from which they have been eroded are either nearly vertical, moderately dipping, or gently dipping.

  4. Cycle of erosion - Wikipedia

    en.wikipedia.org/wiki/Cycle_of_erosion

    The geographic cycle, or cycle of erosion, is an idealized model that explains the development of relief in landscapes. [1] The model starts with the erosion that follows uplift of land above a base level and ends, if conditions allow, in the formation of a peneplain. [1]

  5. Geomorphology - Wikipedia

    en.wikipedia.org/wiki/Geomorphology

    Earth's surface is modified by a combination of surface processes that shape landscapes, and geologic processes that cause tectonic uplift and subsidence, and shape the coastal geography. Surface processes comprise the action of water, wind, ice, wildfire, and life on the surface of the Earth, along with chemical reactions that form soils and ...

  6. Landform - Wikipedia

    en.wikipedia.org/wiki/Landform

    Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type.Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains ...

  7. Hillslope evolution - Wikipedia

    en.wikipedia.org/wiki/Hillslope_evolution

    Following this thought erosion by the sea and lateral stream migration are of prime importance as these processes are effective in removing debris. [5] Unequal activity does also imply there are great disparities between stream erosion near stream channels and apparently unchanged uplands, and between headwaters with limited erosion and the ...

  8. Groundwater sapping - Wikipedia

    en.wikipedia.org/wiki/Groundwater_sapping

    The morphology of channels and valleys created by sapping are highly dependent on regional scale geology, and can be hard to distinguish from features created through alternative processes. Chemical precipitates can be used as indicators of groundwater water discharge implying that a valley or channel may have been formed as a result of sapping.

  9. Headward erosion - Wikipedia

    en.wikipedia.org/wiki/Headward_erosion

    Headward erosion is a fluvial process of erosion that lengthens a stream, a valley or a gully at its head and also enlarges its drainage basin. The stream erodes away at the rock and soil at its headwaters in the opposite direction that it flows. Once a stream has begun to cut back, the erosion is sped up by the steep gradient the water is ...
