A V-shaped valley is a type of valley formed by the erosive action of a river or stream. Over time, the flowing water cuts into the landscape, creating steep sides that resemble the letter "V." This shape is typically found in youthful river systems where the gradient is steep, allowing for rapid erosion. These valleys are often characterized by narrow floors and steep walls, which can be seen in mountainous regions. The process of formation involves both erosion and weathering, with the river continuously carving its path through the landscape, contributing to the overall topography of the area.
