Definition?

Whats a Ridge? I have reson to believe that it its also a name, because my friend Ridge likes halo and school. Deathtopplintheir40s 01:36, 10 October 2007 (UTC)[reply]

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 Halo legend 00 01:33, 22 October 2007 (UTC)[reply]

A Ridge is also a person by the name of Ridge, if a ridge is a person then a ridge cant be a mountain hill or whatever! Eat this you person, Ridge just loves Noodles! --Metal to the Max! 04:49, 22 October 2007 (UTC)

There are several main types of ridges:

Dendritic ridge: In a typical plateau terrain, the stream drainage valleys will leave intervening ridges. These are by far the most common ridges. These ridges usually represent slightly harder rock, but not always -- they are often simply because there were larger joint spaces 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, very long, very even, very straight ridges are formed due to the fact that they're 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.

Crater ridges: Large meteorite strikes typically form large impact craters bordered by circular ridges.

Volcanic caldera ridges: Large volcanoes often leave collapsed central calderas that are bordered by circular ridges.

Thrust fault ridges: Thrust 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 glaciers. Halo legend 00 04:50, 22 October 2007 (UTC)[reply]

Smaller forms than mountain ridges

Can be of much smaller dimensions. For instance a tectonic compressional bend of moderate extent and similar geomorphological forms. Article must accommodate all. Arminden (talk) 07:42, 9 June 2022 (UTC)[reply]

Types; systematic, sourced list needed

They need to be ordered. There is no systematic organisation of the listed types by logical criteria: by genesis (volcanic & magmatic, tectonic & seismic, ice, whatever), by topography...

And are these really THE MAIN TYPES?? I wonder. Looks like quite a random list. "Reef" as main form? And the "reef" is the only sourced one in the entire list. Arminden (talk) 20:08, 16 August 2022 (UTC)[reply]
