These forces originate outside the Earth\u2019s crust and derive their energy primarily from the Sun. Through continuous interaction with atmosphere, hydrosphere, and biosphere, Exogenic Forces slowly but persistently modify relief features over geological time. Although their effects appear gradual, long-term action causes extensive transformation of mountains, plateaus, plains, and coastal regions across the planet.<\/span><\/p>\n<h2><b>Exogenic Forces Definition<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Exogenic Forces refer to geomorphic processes driven by external agents such as wind, water, ice, waves, and biological activity that act on Earth\u2019s surface. These processes include weathering, erosion, transportation, and deposition, collectively responsible for denudation. Unlike internal tectonic forces that build landforms, Exogenic Forces predominantly reduce elevation by wearing down rocks through mechanical stress, chemical reactions, and gravitational movement, reshaping landscapes continuously under the influence of solar energy.<\/span><\/p>\n<h2><b>Exogenic Forces Process<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Exogenic Forces operate through a
