Wishbone - Wikipedia, the free encyclopedia The Wishbone formation is an offensive formation in American football. The wishbone, known in anatomy as the furcula, is a sternum bone found in birds which is shaped like the letter Y. It is used as an attachment point for the wing muscles. In automobiles, a wishbone is a suspension component which resembles the avian bone. en.wikipedia.org /wiki/Wishbone   (262 words)

Star formation - Wikipedia, the free encyclopedia Star formation is the process by which gas in molecular clouds change into the ball of plasma we call a star. In high mass stars, the length of the star formation process is comparable to the other timescales of their evolution, much shorter, and the process is not so well defined. The radiation from the protostar and early star has to be observed in infrared astronomy wavelengths, the extinction caused by the rest of the cloud where it is being formed is usually too big to allow us to observe it in the visual part of the spectrum. en.wikipedia.org /wiki/Star_formation   (449 words)

Formation (football) - Wikipedia, the free encyclopedia The 3-3-4 formation was similar to the WW with the notable exception of having an inside-forward (as opposed to centre-forward) deployed as a midfield schemer alongside the two wing-halves. Formations are described as the number of players in each area from the defensive line (not including the goalkeeper). This formation was successfully used by fellow countryman Gusztáv Sebes in the Hungarian national team of the early 1950s. en.wikipedia.org /wiki/Formation_(football)   (3024 words)

Formation evaluation - Wikipedia, the free encyclopedia Mud logging is a well logging process in which drilling mud and drill bit cuttings from the formation are evaluated during drilling and their properties recorded on a strip chart as a visual analytical tool and stratigraphic cross sectional representation of the well. This voltage is therefore proportional to the resistivity of the formation. Thus the presence or absence of gamma rays in a section of borehole is an indication of the amount of shale or clay in the surrounding formation. en.wikipedia.org /wiki/Formation_evaluation   (3396 words)

Chalk - Wikipedia, the free encyclopedia The Chalk Formation is a European stratigraphic unit in the upper Cretaceous period. Chalk is formed in shallow waters by the gradual accumulation of the calcite mineral remains of micro-organisms over millions of years. Chalk is a soft, white, porous form of limestone composed of the mineral calcite. en.wikipedia.org /wiki/Chalk   (276 words)

Back-formation - Wikipedia, the free encyclopedia Back formation becomes a kind of folk etymology when it rests on an erroneous understanding of the morphology of the longer word. en.wikipedia.org /wiki/Back-formation   (626 words)

Star - Wikipedia, the free encyclopedia Star formation begins with gravitational instability inside those clouds, often triggered by shockwaves from supernovae or collision of two galaxies (as in a starburst galaxy). Star formation occurs in molecular clouds, large regions of high density in the interstellar medium (though still less dense than the inside of an earthly vacuum chamber). The blown-off outer layers of dying stars include heavy elements which may be recycled during new star formation. en.wikipedia.org /wiki/Star   (1943 words)

Understanding the Soil Soil with stable humus must always be protected to maintain the fertility and productivity of the soil. Soil plasma is that substance in the soil that can spin catabolized remnants of former life into vital threads that are woven together into the fabric of new life through the processes of anabolism. Soil plasma is the liquid portion of the soil. www.rain.org /~sals/Petrik.html   (1943 words)

Soil Classification and Soil Formation Soils that form under coniferous forests tend to be more acidic than those under deciduous forests, and root action is also critical in soil formation. Soils generally have a harder time forming on steep slopes, due to runoff of soil particles during rain events. Soils are classified based on their parent material, texture, structure, and profile. bioag.byu.edu /aghort/aghort100/classif.htm   (1943 words)

Formation Skydiving / Skydiving Formation Skydiving can be practiced in groups of 4, 8 or 16, accompanied by a videoman who films the jump. Formation Skydiving is also being practiced in big formations, not to try and perform the most figures but to make the largest one. Formation Skydiving is a discipline practiced in freefall. www.veloce-skydive.com /vr/uk.index.html   (1943 words)

Shotgun formation - Wikipedia, the free encyclopedia Combining elements of the short punt and spread formations ("spread" in that it had receivers spread widely instead of close to or behind the interior line players), it was said to be like a "shotgun" in spraying receivers around the field like a scatter-shot gun. The Shotgun formation is an alignment used by the offensive team in American and Canadian football. This formation is used by many teams in obvious passing situations, although other teams do use this as their base formation. www.sevenhills.us /project/wikipedia/index.php/Shotgun_formation   (433 words)

Planet - Wikipedia No interstellar planet is known to date, but their existence is considered a plausible hypothesis on the grounds that the results of computer simulations of the origin and evolution of planetary systems often include the formation and subsequent ejection of bodies of significant mass. Uranian planets, or ice giants, are a sub-class of gas giants, distinguished from true Jovians by their depletion in hydrogen and helium and a significant composition of rock and ice. All of the accepted planets in the solar system are named after Roman gods, except for Uranus, which is named after a Greek god, and the Earth which was not seen as a planet by the ancients (instead considered the centre of the universe). en.wikipedia.org /wiki/Planet   (433 words)

Galaxy - Wikipedia, the free encyclopedia Most galaxies are several thousand to several hundred thousand light years in diameter and are usually separated from one another by distances on the order of millions of light years. Clusters of galaxies are often dominated by a single giant elliptical galaxy, which over time tidally destroys its satellite galaxies and adds their mass to its own. In the 1970s it was realized that the total visible mass of galaxies (from stars and gas) does not properly account for the speed of the rotating gas, thus leading to the postulation of dark matter. en.wikipedia.org /wiki/Galaxy   (1561 words)

Learn more about Partner dance in the online encyclopedia. Partner dance may be a basis of a formation dance, a round dance, or a sequence dance. Partner dances are the dances whose basic choreography involves coordinated dancing of two partners, as opposed to individuals dancing alone or individually in a non-coordinated manner, and as opposed to groups of people dancing simultaneously in a coordinated manner. These are kinds of group dance where the dancers form couples and dance either the same routines (pre-choreographed or called) or routines within a common choreohraphy that controls both how the each couple dances together and how each couple moves in accord with other couples. www.onlineencyclopedia.org /p/pa/partner_dance.html   (559 words)

Cell (biology) - Wikipedia, the free encyclopedia The cytoplasm of a eukaryotic cell is surrounded by a plasma membrane. Prokaryotic cells have three architectural regions: appendages called flagella and pili—proteins attached to the cell surface; a cell envelope consisting of a capsule, a cell wall, and a plasma membrane; and a cytoplasmic region that contains the cell genome (DNA) and ribosomes and various sorts of inclusions. This membrane serves to separate and protect a cell from its surrounding environment and is made mostly from a double layer of lipids (fat-like molecules) and proteins. en.wikipedia.org /wiki/Cell_formation   (559 words)

Doushantuo Formation - Wikipedia, the free encyclopedia The Doushantuo Formation is a lagerstätte in Guizhou Province, China that is notable for being one of the oldest fossil beds to contain highly preserved fossils. The whole sequence sits on an unconformity with the underlying Liantuo Formation, which is free of fossils, an unconformity usually being interpreted as a period of erosion. The formation is of particular interest because it appears to cover the boundary between the problematic Ediacaran organisms and the more famous Cambrian Explosion. en.wikipedia.org /wiki/Doushantuo_Formation   (559 words)

Tabor (formation) - Wikipedia, the free encyclopedia This is an article on the military formation called tabor. Tabor is a set of horse-drawn wagons that supported the armies in Europe between Hussites developed a tactics of using the tabors as a self-propelled fortresses. en.wikipedia.org /wiki/Tabor_%28formation%29   (559 words)

Large-scale structure of the cosmos - Wikipedia, the free encyclopedia The existence of this structure escaped notice for so long because it requires locating the position of galaxies in three dimensions, which involves combining location information about the galaxies with distance information from redshifts. Currently, many large structures have been found; stars are organised into galaxies which in turn appear to form clusters and superclusters, separated by voids. This is a collection of absorption lines which appear in the spectral lines of light from quasars, which are interpreted as indicating the existence of huge thin sheets of intergalactic (mostly hydrogen) gas. en.wikipedia.org /wiki/Large-scale_structure_of_the_cosmos   (891 words)

Lesson 1. Soil Formation Soils formed in parent materials over decades, centuries, or millennia may be lost due to accelerated erosion over a period of years or a few decades. Soils are porous natural bodies composed of inorganic and organic matter. That part of the three-dimensional soil body in which the effects of climate and biological activity are most pronounced is the soil solum. organiclifestyles.tamu.edu /soilbasics/soilformation.html   (891 words)

Echelon (disambiguation) - Wikipedia, the free encyclopedia The echelon formation in migratory bird flight, aerial combat, tank warfare, and medieval warfare. Echelon in geology refers to a set of short linear features that overlap or are staggered in a line that runs obliquely to the strike of the individual features. Echelon is a flight simulator series developed by MADIA. en.wikipedia.org /wiki/Echelon   (891 words)

Echelon formation - Wikipedia, the free encyclopedia Echelon formations are also commonly used by civic, or riot police to move crowds either to the left or right. In geology an echelon formation is a set of short linear features that overlap or are staggered in a line that runs obliquely to the strike of the individual features. Use of the formation dates back to ancient infantry and cavalry warfare when attempting to flank an enemy, and persists up to the present day, where it is regularly employed by all branches of the modern armed forces. en.wikipedia.org /wiki/Echelon_formation   (891 words)

Southern England Chalk Formation - Wikipedia, the free encyclopedia The Chalk Formation was laid down under the sea during the Upper Cretaceous period, and was later uplifted at around the same time as the Alps were formed. The Chalk Formation of Southern England is a system of chalk downland in the south of England. Where the chalk hills meet the sea there are white cliffs such as the White Cliffs of Dover, Seven Sisters and The Needles on the Isle of Wight The chalk would once have extended across the English Channel and similar cliff features can be found on the French coast. en.wikipedia.org /wiki/Southern_England_Chalk_Formation   (519 words)

CHALK - LoveToKnow Article on CHALK In certain parts of the formation layers of nodular flints (q.v.) abound; in parts, it is inclined to be sandy, or to contain grains of glauconite which was originally confounded with another green mineral, chlorite, hence the name chloritic marl applied to one of the subdivisions of the chalk. Chalk Scenery.Where exposed at the surface, chalk produces rounded, smooth, grass-covered hills as in the Downs of southern England and the Wolds of Yorkshire and Lincolnshire. In its purest form chalk consists of from 95 to 99% of calcium carbonate (carbonate of lime); in this condition it is composed of a mass of fine granular particles held together by a somewhat feeble calcareous cement. www.1911encyclopedia.org /C/CH/CHALK.htm   (1309 words)

General Information Star formation studies in external galaxies allow us to study modes of star formation and physical conditions that can be very different from those found in our own Galaxy. The large and steadily increasing number of papers on star formation that are based on high resolution studies at X-ray, optical, infrared, millimetre, and radio wavelengths testifies to the vigour and timely appeal of this topic. Despite its luminosity, which enables a complete census of massive star formation to be undertaken in the galaxy, it is still a poorly understood process. www.phys.unsw.edu.au /iau221   (1276 words)

Star Formation, Life, and Death In other cases, a star's death was slower; instead of an explosion, elements from the star's interior zones rose to the surface and were then lost to space when the outer layers blew off. The initial mass of the star is an important factor involved with the life of a star and helps to answer many other questions: how long will the star live, at what temperature will it emit radiation, and at what part of the electromagnetic spectrum will the radiation be emitted. This was accompanied by the release of energy, which made the star begin to shine and in turn halt the gravitational collapse of the star. www.solarviews.com /eng/starformation.htm   (1185 words)

Factors of Soil Formation, Plymouth County Soil mottles are the combination of gray and reddish spots produced by alternating aerated and saturated conditions (oxidation-reduction process) within the soil profile. Soils that occur at lower elevations such as in swales, adjacent to drainage-ways and water bodies, and within depressions generally receive surface runoff from higher elevations and often have a seasonal high water table at a shallow depth. Soil profiles within moderately well drained and poorly drained areas are mottled with irregular spots of brown, yellow and grey colors. members.aol.com /plysoil/formation.html   (1185 words)

Soil Formation, Alaska Science Forum Studies of Alaskan glacial moraines show that recognizable traces of soil formation can be detected as little as fifteen years after moraine deposition, that a surface loam layer can develop there in about 250 years, and that 2,000 years will create a full soil profile. Yet without sunshine soil formation would not occur since it is the sunshine that really powers both the physical and the biochemical weathering necessary to soil formation. Soil at the agricultural project near Big Delta, Alaska, is all post-glacial, and so, is typically younger than 10,000 years--some of it much younger. www.gi.alaska.edu /ScienceForum/ASF5/531.html   (1185 words)
