  2. Weathering - Wikipedia

    en.wikipedia.org/wiki/Weathering

    Thermal stress weathering is an important mechanism in deserts, where there is a large diurnal temperature range, hot in the day and cold at night. [14] As a result, thermal stress weathering is sometimes called insolation weathering, but this is misleading. Thermal stress weathering can be caused by any large change of temperature, and not ...

  3. Denudation - Wikipedia

    en.wikipedia.org/wiki/Denudation

    Denudation incorporates the mechanical, biological, and chemical processes of erosion, weathering, and mass wasting. Denudation can involve the removal of both solid particles and dissolved material. These include sub-processes of cryofracture, insolation weathering, slaking, salt weathering, bioturbation, and anthropogenic impacts. [4]

  4. Historical geology - Wikipedia

    en.wikipedia.org/wiki/Historical_geology

    Weathering, erosion, and deposition are examples of gradual geological processes, taking place over large sections of the geologic time scale. In the rock cycle , rocks are continually broken down, transported, and deposited, cycling through three main rock types: sedimentary , metamorphic , and igneous .

  5. Rock cycle - Wikipedia

    en.wikipedia.org/wiki/Rock_cycle

    Weathering and erosion break the original rock down into smaller fragments and carry away dissolved material. This fragmented material accumulates and is buried by additional material. While an individual grain of sand is still a member of the class of rock it was formed from, a rock made up of such grains fused together is sedimentary.

  6. Aeolian processes - Wikipedia

    en.wikipedia.org/wiki/Aeolian_processes

    Wind erosion of soil at the foot of Chimborazo, Ecuador Rock carved by drifting sand below Fortification Rock in Arizona (Photo by Timothy H. O'Sullivan, USGS, 1871). Aeolian processes, also spelled eolian, [1] pertain to wind activity in the study of geology and weather and specifically to the wind's ability to shape the surface of the Earth (or other planets).

  7. Ore genesis - Wikipedia

    en.wikipedia.org/wiki/Ore_genesis

    Erosion of non-ore material. Deposition by sedimentary processes, including winnowing, density separation (e.g.; gold placers). Weathering via oxidation or chemical attack of a rock, either liberating rock fragments or creating chemically deposited clays, laterites, or supergene enrichment. Deposition in low-energy environments in beach ...

  8. Deposition (geology) - Wikipedia

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

    Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.

  9. Rock (geology) - Wikipedia

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

    Before being deposited, sediments are formed by weathering of earlier rocks by erosion in a source area and then transported to the place of deposition by water, wind, ice, mass movement or glaciers (agents of denudation). [5]
