A landform refers to a natural physical feature of the Earth's surface, shaped by geological processes such as plate tectonics, erosion, and weathering. These diverse structures include mountains, plateaus, valleys, and sedimentary basins, each formed by unique combinations of geological forces. The creation of landforms is an ongoing process driven by the interaction between internal Earth dynamics and external surface agents. For instance, volcanic activity can create new islands or mountains, while fluvial processes, such as the movement of water, are responsible for carving out canyons and deltas, demonstrating the continuous reshaping of the planet's topography over immense timescales.
