ridge

Ridge is a term with several related uses in geography, anatomy, and culture. In geomorphology, a ridge is a long, narrow crest that rises above the surrounding terrain. Ridges form by tectonic uplift and folding, by faulting, or by erosion that leaves resistant rock standing as a crest. They commonly run parallel to each other and to adjacent valleys, often serving as drainage divides between watersheds. Prominent examples occur in mountain belts and around mid-ocean ridges, the latter created where tectonic plates diverge and new crust is formed.

In anatomy and paleontology, a ridge refers to an elongated raised crest on a bone or shell. Examples include the iliac crest of the pelvis, the sagittal crest on certain skulls, or the alveolar ridges that house the teeth. Ridges are important landmarks for muscle and ligament attachment and for understanding growth and development.

Ridge is also used as a proper name. It can be a surname or a place name in various regions, and individuals or communities may be identified simply as “Ridge.” In popular culture, notable use includes Ridge Forrester, a long-time character on the American soap opera The Bold and the Beautiful, who appears in many storylines.

Overall, ridge denotes a linear elevated feature across disciplines, with formation and significance varying by context.
