Accretion may refer to:

  • Accretion (astrophysics)
  • Accretion (atmosphere), the process by which water vapor in clouds forms water droplets around nucleation sites.
  • Accretion (meteorology), the process by which a larger hydro-meteor grows by collecting smaller ones lying in its path as it falls through a cloud.
  • Accretion (geology), the increase in size of a tectonic plate by addition of material along a convergent boundary
  • Accretion (coastal management), the process where coastal sediments return to the visible portion of the beach following storm erosion
  • Accretion (finance), predictable changes in the price of certain securities

Famous quotes containing the word accretion:

    Viewed freely, the English language is the accretion and growth of every dialect, race, and range of time, and is both the free and compacted composition of all.
    Walt Whitman (1819–1892)

    It doesn’t matter that your painting is small. Kopecks are also small, but when a lot are put together they make a ruble. Each painting displayed in a gallery and each good book that makes it into a library, no matter how small they may be, serves a great cause: accretion of the national wealth.
    Anton Pavlovich Chekhov (1860–1904)
