  2. 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 ]

  3. Soil mechanics - Wikipedia

    en.wikipedia.org/wiki/Soil_mechanics

    A phase diagram of soil indicating the masses and volumes of air, solid, water, and voids. There are a variety of parameters used to describe the relative proportions of air, water and solid in a soil. This section defines these parameters and some of their interrelationships. [2] [6] The basic notation is as follows:

  4. Water cycle - Wikipedia

    en.wikipedia.org/wiki/Water_cycle

    The diagram also shows how human water use impacts where water is stored and how it moves. [1] The water cycle (or hydrologic cycle or hydrological cycle) is a biogeochemical cycle that involves the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time.

  5. Soil structure - Wikipedia

    en.wikipedia.org/wiki/Soil_structure

    Soil structure describes the arrangement of the solid parts of the soil and of the pore spaces located between them (Marshall & Holmes, 1979). [1] Aggregation is the result of the interaction of soil particles through rearrangement, flocculation and cementation.

  6. File:Soil-phase-diagram.svg - Wikipedia

    en.wikipedia.org/wiki/File:Soil-phase-diagram.svg

    Soil phase diagram showing soil composition. V is for volume, M is for mass. Subscripts s, w, and a stand for soil particles, water and air respectively. Subscripts v and t stand for voids and total respectively. Date: 9 June 2010, 11:05 (UTC) Source: Soilcomposition.png: Author: Derivative work: 5d7ygtr09h; Sjhan81

  7. Soil formation - Wikipedia

    en.wikipedia.org/wiki/Soil_formation

    Soil formation, also known as pedogenesis, is the process of soil genesis as regulated by the effects of place, environment, and history. Biogeochemical processes act to both create and destroy order within soils.

  9. Critical state soil mechanics - Wikipedia

    en.wikipedia.org/wiki/Critical_state_soil_mechanics

    This behavior, critical state soil mechanics simply assumes as a given. For these reasons, critical-state and elasto-plastic soil mechanics have been subject to charges of scholasticism; the tests to demonstrated its validity are usually "conformation tests" where only simple stress-strain curves are demonstrated to be modeled satisfactorily.
