tectonics    音标拼音: [tɛkt'ɑnɪks]
n. 构造学,构造地质学,大地构造学

构造学,构造地质学,大地构造学

tectonics
n 1: the science of architecture [synonym: {architectonics},
{tectonics}]
2: the branch of geology studying the folding and faulting of
the earth's crust [synonym: {tectonics}, {plate tectonics},
{plate tectonic theory}]

Tectonics \Tec*ton"ics\, n.
1. The science, or the art, by which implements, vessels,
dwellings, or other edifices, are constructed, both
agreeably to the end for which they are designed, and in
conformity with artistic sentiments and ideas.
[1913 Webster]

2. (Geol. & Phys. Geog.) the branch of geology concerned with
the rock structures and external forms resulting from the
deformation of the earth's crust; also, similar studies of
other planets. Also called {structural geology}.
[PJC]

{plate tectonics} a geological theory which considers the
earth's crust as divided into a number of large relatively
rigid plates, which move relatively independently on the
more plastic asthenosphere under the influence of magmatic
upwellings, so as to drift apart, slide past, or collide
with each other, causing the formation, breakup, or
merging of continents, and causing volcanism, the building
of mountain ranges, and the subduction of one plate
beneath another. In recent decades a large body of data
have accumulated to support the theory and provide some
details of the mechanisms at work. One set of supporting
observations consists of data showing that the continents
have slowly moved relative to each other over long periods
of time, a phenomenon called {continental drift}. Africa
and South America, for example, have apparently moved
apart from a connected configuration at about 2 to 3 cm
per year over tens of millions of years.
[PJC]

  • Tectonics - Wiley Online Library - AGU Publications
    Tectonics presents original research articles that describe and explain the evolution, structure, and deformation of Earth’s lithosphere including across the range of geologic time
  • Tectonics - Wikipedia
    Tectonics (from Ancient Greek τεκτονικός tektonikós 'pertaining to building ' via Latin tectonicus) [1] are the processes that result in the structure and properties of the Earth's crust and its evolution through time The field of planetary tectonics extends the concept to other planets and moons [2][3]
  • Tectonics | Plate Boundaries, Earthquakes Faults | Britannica
    tectonics, scientific study of the deformation of the rocks that make up the Earth’s crust and the forces that produce such deformation It deals with the folding and faulting associated with mountain building; the large-scale, gradual upward and downward movements of the crust (epeirogenic movements); and sudden horizontal displacements
  • Plate tectonics | Definition, Theory, Facts, Evidence | Britannica
    plate tectonics, theory dealing with the dynamics of Earth’s outer shell—the lithosphere—that revolutionized Earth sciences by providing a uniform context for understanding mountain-building processes, volcanoes, and earthquakes as well as the evolution of Earth’s surface and reconstructing its past continents and oceans
  • Plate Tectonics - National Geographic Society
    Plate tectonics is a scientific theory that explains how major landforms are created as a result of Earth’s subterranean movements The theory, which solidified in the 1960s, transformed the earth sciences by explaining many phenomena, including mountain building events, volcanoes, and earthquakes
  • Plate Tectonics: Definition, Theory, Types, Facts, Evidence
    Tectonic plates are large, irregular-shaped slabs of rock making up the Earth’s crust and upper mantle They are found to float on top of a semi-liquid layer of rock called the asthenosphere Plate tectonic theory began in 1915 when Alfred Wegener proposed his theory of continental drift
  • Geology - Plate Tectonics, Earthquakes, Volcanoes | Britannica
    The subject of tectonics is concerned with the Earth’s large-scale structural features It forms a multidisciplinary framework for interrelating many other geologic disciplines, and thus it provides an integrated understanding of large-scale processes that have shaped the development of our planet
  • Plate Tectonics—The Unifying Theory of Geology
    Plate tectonics has revolutionized the way we view large features on the surface of the Earth Earth’s internal processes were previously thought to operate in a vertical fashion, with continents, oceans, and mountain ranges bobbing up and down, without much sideways movement
  • How Plate Tectonics Shaped the World We Live In
    Tectonics and Us: Living on a Restless Planet For all its ancient grandeur, plate tectonics is not a relic of the past It is alive, still sculpting the Earth beneath our cities and fields Humanity’s greatest civilizations have often flourished near tectonic boundaries—where fertile volcanic soils and fresh mountain rivers provide life
  • Tectonics - Latest research and news - Nature
    Tectonics is the study of the structural geology of the Earth and other planetary bodies, and the local and regional processes that created that rock geometry
