The term ‘exogenic’ refers to external processes and phenomena that occur on or above the surface of the earth. Comet and meteoroid impacts, the tidal force of the moon and the radiation from the sun are all exogenic. Weathering effects and erosion are also exogenic processes.
A common example of an exogenous process that is not as a result of bodies in space is erosion. Erosion happens as a result of wind, water, ice, or people, animals, or plants digging in the Earth. Some other examples of exogenous process are rainfall, snowfall, hailstorm, erosion, tsunamis, avalanches, winds, wave currents etc.
