Small valleys are a type of landform that are typically narrow and shallow. They are often found in areas with rolling hills or mountains, and can be formed by the action of rivers or glaciers. The term 'small valley' can refer to four different types of landforms: DELLS (5 letters), GLENS (5 letters), swales (6 letters), and COULEES (7 letters). Dell is a term used to describe a small, wooded valley, while glen is a term used to describe a narrow valley with steep sides. Swales are shallow depressions in the land, and COULEES are deep, narrow valleys with steep sides. All of these landforms are considered small valleys, and they are all characterized by their narrow and shallow shape.
