Explanation:
Sigmund Freud was a great neurologist known very much whose findings and works pushed through from 1856-1939.
He became popularly known as the founding father of psychoanalysis. Psychoanalysis emphasizes the influence of our unconscious mind on our behavior. As part of this theory, Freud believed the mind was composed of three parts: the id, ego, and superego. The preconscious mind is an important part of this process. The preconscious contains thoughts that are unconscious but can be easily recalled. Let's take a look at these concepts with a bit more detail.
Intrusive igneous rocks include gabbro, granite, and diorite. Each rock differs in that it was created by a separate silica-containing magma.
Despite having different silica concentrations, granite, diorite, and gabbro are all products of magmas. Gabbro is a typical rock that contains 45% to 55% silica. With a silica content ranging from 55% to 65%, diorite is a middle-ground rock. With a silica concentration of more than 65%, granite is an acidic rock.
The most common elements in the Earth's crust, silicon and oxygen, are combined to form silica, also known as silicon dioxide (SiO 2). Silica, which makes up the majority of more than 95 percent of all known rocks, makes up 59 percent of the Earth's crust. Quartz, which is by far the most prevalent crystalline variety of silica, tridymite, and cristobalite are the other two.
