Solution
A V-shaped cross-section of a river valley occurs when the two sides are close and steep, with little level terrain in between. They occur in the upper reaches of a river.
The contour lines of this type of valley are in inverted V-shape, decreasing inward. The section shows a V-shaped landform.
