The process of accretion is the process of adding material (typically gaseous matter) to a tectonic plate or a landmass as a result of the gravitational forces.Most astronomical objects, such as galaxies, stars, and planets, are formed by the accretion processes<span>. From the given options the following statement is true about the process of accretion: A.</span><span>It enlarges continental landmasses and forms mountains along the edges of continents.</span>
Answer: A. It enlarges continental landmasses and forms mountains along the edges of continents.
The accretion is a process in which small objects, matter or particles gets aggregated to form a large object, landmass due to the affect of gravitational force acting on these entities. Example of accretion process includes formation of galaxies, stars, planets and mountains. Mountains are formed at the edges of continents because of accumulation of debris and sediments released between the edges is an example of accretion process.
Mutation is random because there is really no way of knowing whether a child will inherit it, whereas natural selection is predisposed in either parent.
