The meaning of ACCRETION is the process of growth or enlargement by a gradual buildup. How to use accretion in a sentence. Did you know?
Oct 31, 2024 · Search for: 'accretion' in Oxford Reference ». 1 Process by which an inorganic body grows in size by the addition of new particles to its exterior. It is the mechanism by which primitive planetary bodies are believed to form as a result of the accumulation of minute, cold, homogeneous particles (homogeneous accretion).
Summary. In planetary science, accretion is the process in which solids agglomerate to form larger and larger objects, and eventually planets are produced. The initial conditions are a disc of gas and microscopic solid particles, with a total mass of about 1% of the gas mass. These discs are routinely detected around young stars and are now ...

Definition. Accretion is the process by which dust, gas, and small particles in space come together to form larger bodies, such as planets and other celestial objects. This process is crucial in the formation and evolution of the solar system, linking the formation of small bodies with larger planetary structures and their differentiation over ...
