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.
<h3><u>Processes that form different fossil types:</u></h3>
The remained parts and elements of an organism that live several years ago is called as fossils.
Due to natural processes like weathering, soil erosion and other geological activities fossils are hard to preserve.
Carbonization, permineralization, recrystallization and replacement are the fossil formation processes.
Carbonization is the chemical reaction forming the thin film of carbon of the organic material.
Permineralization includes the fossils of bones and teeth. The recrystallization process is responsible for changing the micro-structure of the organic materials to form the fossils.
The kidney filters about 200 quarts of blood to remove about 2 quarts of waste and excess water. That excess water and waste is sent to the bladder and leaves the body as urine.
