Exogeenisia

Exogeenisia is a term used in some scientific contexts, particularly in geology and planetary science, to describe processes or substances originating from outside a given system. It is the opposite of endogeenisia, which refers to internal origins. For instance, in geology, exogeenisia can refer to geological formations or deposits that are formed by external forces rather than internal ones. Examples include erosion, weathering, and sedimentation, all of which are influenced by external factors like wind, water, and ice. The material deposited through these processes is considered exogeenous.

In planetary science, exogeenisia can relate to the composition or modification of a planet's surface. It might refer to the impact of meteorites, comets, or interplanetary dust, which contribute external material and energy to a planet. Similarly, atmospheric phenomena driven by solar radiation or external stellar influences can be considered exogeenous. The study of exogeenous processes helps scientists understand the evolution of celestial bodies and the sources of their surface materials, distinguishing them from materials that originated from the planet's own internal processes like volcanic activity or tectonic shifts.
