Ridges
A ridge is a basic type of terrain . It can be described geometrically as a uniaxially convex elongated bulge of a surface, the cross section of the ridge having a rounded vertex . This is usually the case in the low mountain range and in the hill country , less so in the high mountains .
The meaning of a ridge differs depending on how the terrain continues at either end of the ridge. If both ends fall to a lower level, the ridge is a mountain . If the level rises at both ends, the ridge is more of a threshold or a ridge . If the level rises at one end and falls at the other end, it is more like the foothills of a mountain. It also happens that a ridge splits into two or more directions at one or both ends. Finally, the height profile of the crest of the ridge is also important for describing a ridge. It can run approximately horizontally, but it can also have a gradient from one end to the other.
