What shape do contour lines form to indicate a ridge?

Contour lines that indicate a ridge typically form a U-shape or a V-shape, with the open end of the U or V facing downhill. This shape reflects the elevation change in the terrain; as you move uphill, the lines create a series of peaks or summits that characterize ridges. The V-shaped formation often represents a divided slope, where the apex of the V points towards lower elevation terrain. Understanding this pattern is crucial for land navigation as it helps in visualizing the landscape and determining the direction of the slope or the highest points in an area. Recognizing U and V shapes in contour lines is essential for navigating mountainous or hilly terrains effectively.
