When several related landforms combine, they form extensive landscapes representing large surface tracts of the Earth. Each landform has distinct physical characteristics such as shape, size, structure, material composition, and elevation. These features develop gradually due to slow acting geomorphic processes such as erosion, weathering, transportation, and deposition, operating through natural agents like rivers, wind, waves, glaciers, and groundwater over geological time scales.<\/span><\/p>\n<h2><b>Erosional Landforms<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Erosional landforms are surface features shaped primarily by the removal of soil and rock through erosional agents like running water, wind, waves, and ice. These landforms develop where erosion dominates over deposition, often in regions of high relief, steep gradients, strong winds, or turbulent water flow. Examples include valleys, gorges, potholes, caves, arches, stacks, pedestals, yardangs, and deflation basins. Such landforms reflect the intensity, direction, duration, and energy of erosional processes acting upon different rock structures and climatic conditions.<\/span><\/p>\n<h2><b>Erosional Landforms Features<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Erosional landforms display clear physical traits shaped by continuous removal of material under specific geomorphic controls.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Structural Control: Shape depends on rock hardness, bedding planes, and joint
