What does «acreción» mean in Spanish?
- In mineralogy, growth by juxtaposition; a process of accumulation of materials (an aggregation of smaller bodies) on a given surface or around the core of a mass, and this involves an increase in its size or extent.
- In geology, growth of continental masses by addition of terrain, called continental accretion. This material may be sediment, volcanic arcs, seamounts or other igneous features.
- In meteorology, the process by which water vapor in clouds forms water droplets around nucleation sites.
- In astrophysics, accretion is the accretion of particles onto a massive object by gravitationally attracting more matter, typically gaseous matter, into an accretion disk. Most astronomical objects, such as galaxies, stars and planets, are formed by accretion processes. In the case of stars, the mass accretion of a star is the addition of matter onto it from another star or interstellar matter. History
- (disco de acreción) In astronomy, a disk of dust and gas falling toward a massive object, following an orbital trajectory perpendicular to its axis of rotation.
