A ridge is a geological feature that features a continuous elevational crest for some distance. Ridges are usually termed hills or mountains as well, depending on size. There are several main types of ridges:

  • Dendritic ridge: In typical dissected plateau terrain, the stream drainage valleys will leave intervening ridges. These are by far the most common ridges. These ridges usually represent slightly more erosion resistant rock, but not always – they often remain because there were more joints where the valleys formed, or other chance occurrences. This type of ridge is generally somewhat random in orientation, often changing direction frequently, often with knobs at intervals on the ridge top.
  • Stratigraphic ridge: In places such as the Ridge-and-valley Appalachians, long, even, straight ridges are formed because they are the uneroded remaining edges of the more resistant strata that were folded laterally. Similar ridges have formed in places such as the Black Hills, where the ridges form concentric circles around the igneous core. Sometimes these ridges are called "hogback ridges".
  • Oceanic spreading ridge: In tectonic spreading zones around the world, such as at the Mid-Atlantic Ridge, the volcanic activity forming new plate boundary forms volcanic ridges at the spreading zone. Isostatic settling and erosion gradually reduce the elevations moving away from the zone.
  • Volcanic caldera ridges: Large volcanoes often leave collapsed central calderas that are bordered by circular ridges.
  • Fault ridges: Faults often form escarpments. Sometimes the tops of the escarpments form not plateaus, but slope back so that the edges of the escarpments form ridges.
  • Dune ridges: In areas of large-scale dune activity, certain types of dunes result in sand ridges.
  • Moraines and eskers: Glacial activity may leave ridges in the form of moraines and eskers. An arête is a thin ridge of rock that is formed by glacial erosion.
