  2. Exogeny - Wikipedia

    en.wikipedia.org/wiki/Exogeny

    In geography, exogenous processes, unlike endogenic processes, originate from external forces acting on the Earth and other planetary bodies, rather than from internal geological activity. Weathering , erosion , transportation and sedimentation are the main exogenous processes.

  3. Denudation - Wikipedia

    en.wikipedia.org/wiki/Denudation

    Endogenous processes such as volcanoes, earthquakes, and tectonic uplift can expose continental crust to the exogenous processes of weathering, erosion, and mass wasting. The effects of denudation have been recorded for millennia but the mechanics behind it have been debated for the past 200 years [ when? ] and have only begun to be understood ...

  4. Habitat fragmentation - Wikipedia

    en.wikipedia.org/wiki/Habitat_fragmentation

    The two types of processes that can lead to habitat fragmentation are known as endogenous processes and exogenous processes. Endogenous is a process that develops as a part of species biology so they typically include changes in biology, behavior, and interactions within or between species.

    Solidified lava flow in Hawaii Sedimentary layers in Badlands National Park, South Dakota Metamorphic rock, Nunavut, Canada. Geology (from Ancient Greek γῆ (gê) ' earth ' and λoγία () ' study of, discourse ') [1] [2] is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over ...

  6. Ore genesis - Wikipedia

    en.wikipedia.org/wiki/Ore_genesis

    Superficial deposits processes of ore formation include; 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.

  7. Exogenous bacteria - Wikipedia

    en.wikipedia.org/wiki/Exogenous_bacteria

    Exogenous bacteria are microorganisms introduced to closed biological systems from the external world. [citation needed] They exist in aquatic and terrestrial environments, as well as the atmosphere. Microorganisms in the external environment have existed on Earth for 3.5 billion years. [1] Exogenous bacteria can be either benign or pathogenic.

  8. Climatic geomorphology - Wikipedia

    en.wikipedia.org/wiki/Climatic_geomorphology

    Desert geomorphology or the geomorphology of arid and semi-arid lands shares many landforms and processes with more humid regions. One distinctive feature is the sparse or lacking vegetation cover, which influences fluvial and slope processes, related to wind and salt activity. [4]

  9. Earth's critical zone - Wikipedia

    en.wikipedia.org/wiki/Earth's_Critical_Zone

    Earth's critical zone. Illustration by Critical Zone Observatories (CZO) based on a figure in Chorover et al. 2007.. Earth's critical zone is the “heterogeneous, near surface environment in which complex interactions involving rock, soil, water, air, and living organisms regulate the natural habitat and determine the availability of life-sustaining resources” (National Research Council ...
