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.
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 ...
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 time.

Immediately after their formation the erosion of the mountains began under the influence of exogenous processes during the Permian period. During the Triassic period, which began about 225 million years ago, what is now central Europe was sometimes above and sometimes below sea level.
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.
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.
This is commonly known as Tobler's first law of geography, summarized as "everything is related to everything else, but nearby objects are more related than distant objects". In ecology, there are two important sources of spatial autocorrelation, which both arise from spatial-temporal processes, such as dispersal or migration: [11]
