  2. Weathering - Wikipedia

    en.wikipedia.org/wiki/Weathering

    Weathering is the deterioration of rocks, soils and minerals (as well as wood and artificial materials) through contact with water, atmospheric gases, sunlight, and biological organisms. It occurs in situ (on-site, with little or no movement), and so is distinct from erosion, which involves the transport of rocks and minerals by agents such as ...

  3. Abrasion (geology) - Wikipedia

    en.wikipedia.org/wiki/Abrasion_(geology)

    Abrasion (geology) Abrasion is a process of weathering that occurs when material being transported wears away at a surface over time, commonly happens in ice and glaciers. The primary process of abrasion is physical weathering. Its the process of friction caused by scuffing, scratching, wearing down, marring, and rubbing away of materials.

  4. Spall - Wikipedia

    en.wikipedia.org/wiki/Spall

    Spall are fragments of a material that are broken off a larger solid body. It can be produced by a variety of mechanisms, including as a result of projectile impact, corrosion, weathering, cavitation, or excessive rolling pressure (as in a ball bearing). Spalling and spallation both describe the process of surface failure in which spall is shed.

  5. Hydraulic action - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_action

    It is a mechanical process, in which the moving water current flows against the banks and bed of a river, thereby removing rock particles. A primary example of hydraulic action is a wave striking a cliff face which compresses the air in cracks of the rocks. This exerts pressure on the surrounding rock which can progressively crack, break ...

  6. Scree - Wikipedia

    en.wikipedia.org/wiki/Scree

    The formation of scree and talus deposits is the result of physical and chemical weathering acting on a rock face, and erosive processes transporting the material downslope. There are five main stages of scree slope evolution: (1) accumulation, (2) consolidation, (3) weathering, (4) encroaching vegetation, and finally, (5) slope degradation.

  7. Frost weathering - Wikipedia

    en.wikipedia.org/wiki/Frost_weathering

    Frost weathering is a collective term for several mechanical weathering processes induced by stresses created by the freezing of water into ice. The term serves as an umbrella term for a variety of processes, such as frost shattering, frost wedging, and cryofracturing. The process may act on a wide range of spatial and temporal scales, from ...

  8. Honeycomb weathering - Wikipedia

    en.wikipedia.org/wiki/Honeycomb_weathering

    Honeycomb weathering, also known as honeycombs, honeycombed sandstone, is a form of cavernous weathering that consists of regular, tightly adjoining, and commonly patterned cavities that are developed in weathered bedrock; are less than 2 cm (0.79 in) in size; and resemble a honeycombed structure. Honeycombs also been called alveoli, lacework ...

  9. Soil mechanics - Wikipedia

    en.wikipedia.org/wiki/Soil_mechanics

    All rock types (igneous rock, metamorphic rock and sedimentary rock) may be broken down into small particles to create soil. Weathering mechanisms are physical weathering, chemical weathering, and biological weathering [1][2][3] Human activities such as excavation, blasting, and waste disposal, may also create soil.
