Going beyond just the human perspective, landforms are consequential for all life forms. Landforms have effects on water reception and subsequent movements, soil development, microclimatic conditions, primary and secondary productivity, ease or difficulty of animal movement and plant dispersal, impacts of episodic events, e.g., winds, floods, fires. Geomorphogenesis, the development of landforms, occurs as the result of one or more of these surficial processes: weathering (physical and chemical) of geologic materials, overland water movement,
