Accretion is the process by which matter is accumulated by gravitational forces. While the accumulation of matter can lead to the formation of objects that spin, such as stars and planets, accretion itself does not inherently involve spinning.
Accretion can be modeled using various mathematical and physical principles, such as conservation of mass, conservation of angular momentum, and gravitational interactions between particles. The process of accretion involves the gradual accumulation of material onto a larger body, such as a star or planet, due to gravitational attraction. Modeling accretion requires understanding the dynamics and mechanisms involved in the accretion process, which can be represented using mathematical equations and simulations.
Accretion is important because it is the process by which celestial objects like stars and planets form. It involves the accumulation of matter, usually due to gravitational attraction. Understanding accretion helps us comprehend the formation and evolution of celestial bodies, which is crucial in studying the universe's origins and dynamics.
Planets are formed through a process called accretion, where dust and gas in a planetary disk gradually come together to form larger and larger bodies. Gravitational forces eventually cause these bodies to collide and merge, leading to the formation of planets.
The two critical phases for formation stages are the accretion phase and the differentiation phase. During the accretion phase, dust and gas in a protoplanetary disk collide and stick together, forming larger bodies that eventually become planets. In the differentiation phase, these bodies undergo melting and segregation of materials, leading to the formation of distinct layers based on density, such as cores, mantles, and crusts. These phases are essential for the development of planetary structures and compositions.

Terrane accretion
A mountain range formed due to terrane accretion is known as a composite mountain range. This type of mountain range is formed when different land masses or terranes are added to the edge of a continent through tectonic processes, leading to the uplift and formation of mountains. Examples of composite mountain ranges include the Alps in Europe and the Sierra Nevada in North America.
Terrace accretion is not specifically associated with a single mountain; rather, it is a geomorphological process that occurs in various mountainous regions. It involves the formation of terraces along riverbanks or on slopes due to sediment deposition and erosion, often seen in areas where rivers cut into the landscape. This process can be observed in many mountain ranges globally, such as the Himalayas or Andes, where geological activity influences river dynamics.

The accretion of matter due to gravity.
This process of collision and joining of crustal fragments to a continent is known as terrane accretion. It occurs when tectonic plates collide, causing the fragments to be added to the edge of the continent. This can result in the formation of mountain ranges and changes in the overall geology of the continent.
mountain building
The mountain range formed over millions of years through the accretion of sediment and rock particles. The artist's style evolved through the accretion of various influences and experiences. The accretion of dust on the furniture indicated that no one had been in the room for quite some time.

Gravity, of course has a central role in formation of planets. It's believed that the planets origin can be traced to the debris swirling around a young star. The term used for coming together of particles or bodies and joining together is 'accretion'. Gravity is the reason behind accretion . Small debris join together due to accretion and this accretion occurs further to give rise to larger and larger bodies like planets . Without gravity, this could never have occurred.
Our planet was formed about four and a half billion years ago, and it is likely that there were mountains from the beginning. The messy process of planetary formation itself, involving the accretion of mass from various smaller bodies, is not likely to produce a perfectly spherical surface.
