What is ridge shape?

A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for some distance. The sides of the ridge slope away from narrow top on either side. Ridges are usually termed hills or mountains as well, depending on size.

What does a ridge look like?

What are the type of ridges?

The ridge like seafloor highs with various geological origins can be classed into mid-ocean ridges, transverse ridges related to transform faults, hot spot/mantle plume originated ridges, microcontinent rifted from major continent, intra-plate arc formed by interaction of two oceanic plates, and tectonic ridges …

How do ridges form?

A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.

Is a crest a ridge?

A long narrow upper section or crest: the ridge of a wave.

What is ridge describe?

1 : an elevated body part or structure. 2a : a range of hills or mountains. b : an elongate elevation on an ocean bottom. 3 : an elongate crest or a linear series of crests. 4 : a raised strip (as of plowed ground)

How do you identify a valley?

A valley can be “V” or “U” shaped and often can be seen as a “negative” to a ridge. On a map, valleys are represented by the same contour shape as ridges with the difference being the the wide openings are at lower elevation.

What is an example of a ridge?

The definition of a ridge is a long, narrow crest of something. An example of a ridge is the strip of mountains in the Southeast area of Mt. Everest from Nepal. An example of a ridge is along an animal’s backbone.

Why are mid ocean ridges ridge shaped?

As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt. The speed of spreading affects the shape of a ridge – slower spreading rates result in steep, irregular topography while faster spreading rates produce much wider profiles and more gentle slopes.

What is submarine mountain?

Undersea mountain ranges are mountain ranges that are mostly or entirely underwater, and specifically under the surface of an ocean. If originated from current tectonic forces, they are often referred to as a mid-ocean ridge. In contrast, if formed by past above-water volcanism, they are known as a seamount chain.

What is the difference between a ridge and a valley?

Ridge (Also: Arete or Spur) – A continuous elevated terrain with sloping sides. Valley (Also: Gully, Draw, Couloir) – Long depression in the terrain that has a narrow elevated side and a wide lower opening. A valley can be “V” or “U” shaped and often can be seen as a “negative” to a ridge.

What is the difference between a ridge and a mountain?

@peterf A mountain range is a series of mountains together in one region, such as the Pyrénées in France or the Andes. A ridge is the top of a mountain usually flat and horizontal rather than than a point. If the mountain ends in a point it is called a peak.
