A chine /ˈtʃaɪn/ is a steep-sided river valley where the river flows to the sea through, typically, soft eroding coastal cliffs of sandstone or clays. The word is still in use in central Southern England—notably in East Devon, Dorset, Hampshire and the Isle of Wight—to describe such topographical features. However, 'bunny' is also used to describe a chine in Hampshire, as noted below.
Chines appear at the outlet of small river valleys when a particular combination of geology, stream volume and coastal recession rate creates a knickpoint, usually starting at a waterfall at the cliff edge, that initiates rapid erosion and deepening of the stream bed into a gully leading down to the sea.
All chines are in a state of constant change due to erosion. The Blackgang Chine on the Isle of Wight, for example, has been destroyed by landslides and coastal erosion during the 20th century. As the walls of the chines and cliffs are so unstable and erode continually, particularly those of the south coast of the Isle of Wight, the strata are clearly visible. Chines are, therefore, very important for their fossil records, their archaeology and the unique flora and fauna, such as invertebrates and rare insects, for which they provide shelter.
A chine in boating refers to a sharp change in angle in the cross section of a hull. A hull without chines has a gradually curving cross section. The term hard chine indicates an angle with little rounding, where a soft chine would be more rounded, but still involve the meeting of distinct planes. Chine log construction is a method of building hard chine boat hulls. Hard chines are common in plywood hulls, while soft chines are often found on fiberglass hulls.
The oldest type of engineered boats are dugout canoes, which were built by hollowing out a log. These designs generally had rounded bottoms, which made best use of the round shape of the logs. Traditional planked hulls in most cultures are built by placing wooden planks oriented parallel to the waterflow and attached to bent wooden frames. This also produced a rounded hull, generally with a sharp bottom edge to form the keel. Planked boats were built in this manner for most of history.
The first hulls to start incorporating hard chines were probably shallow draft cargo carrying vessels used on rivers and in canals. The barge and later the scow used a flat bottom and near vertical sides, which provided the maximum cargo carrying capacity (in both space and displacement) available for a given depth of water.
In aircraft design, a chine may be one of several features:
A chine shaped fuselage may be described as a fuselage featuring sideways extensions, or long extensions of the wing roots along the fuselage. Chines first appeared on the Lockheed A-12 precursor of the SR-71 Blackbird, where they formed forward extensions of the wing roots along the fuselage sides into which they blended.
The Lockheed Martin F-22 Raptor has chines that lead to the leading-edge extensions that are blended into the engine air intakes.
Bailar de lejos no es bailar
Es como estar bailando solo
Tú bailando en tu volcán y a dos metros de ti
Bailando yo en el polo
Probemos una sola vez
Bailar pegados con más fuego
Abrazados al compás, sin separar jamás
Tu cuerpo de mi cuerpo
Bailar pegados es bailar
Igual que baila el mar con los delfines
Corazón con corazón en un solo salón, dos bailarines
Abrazadísimos los dos, acariciándonos
Sintiéndonos la piel, nuestra balada va a sonar
Vamos a probar, probar el arte de volar
Bailar pegados es bailar
Bailar pegados es bailar, es bailar
Verás la música después
Te va pidiendo un beso a gritos
Y te sube por los pies,
Un algo que no ves, lo que nunca se ha escrito
Bailar pegados es bailar
Igual que baila el mar con los delfines
Corazón con corazón en un solo salón, dos bailarines, oh
Abrazadísimos los dos, acariciándonos
Sintiéndonos la piel, nuestra balada va a sonar
Vamos a probar, probar el arte de volar
Bailar pegados es bailar
