Geomorphology is the scientific discipline that investigates the origin, evolution, and spatial distribution of landforms and the processes that shape Earth’s surface across a range of temporal and spatial scales. It integrates principles from geology, hydrology, climatology, soil science, and geophysics to analyze fluvial, glacial, aeolian, coastal, tectonic, and mass-wasting processes. Quantitative geomorphology employs field measurements, remote sensing, numerical modeling, and geochronological techniques to constrain rates of erosion, sediment transport, and landscape adjustment, providing a mechanistic framework for understanding surface dynamics, surface–climate–tectonics interactions, and the development of topography on Earth and other planetary bodies.
In the forests of the southeastern United States, dense tree cover dominates most landscapes. That's why the Appalachian Trail is sometimes nicknamed "The Green Tunnel." But avid hikers know that often in the Southeast, they'll ...
