Landform development refers to the processes that shape the Earth's surface over time. These processes include erosion, weathering, and tectonic activity, which can create various landforms such as mountains, valleys, and plateaus. Factors like climate, vegetation, and human activity also influence how landforms evolve. The interaction between natural forces and geological materials leads to the formation of distinct features. For example, rivers can carve out canyons, while glaciers can create fjords. Understanding landform development helps scientists predict changes in landscapes and assess environmental impacts.
