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.

<span>Gouverneur Morris (1752-1816) was an American politician, public official and diplomat. Born into a prominent New York family, he earned election to the state’s provincial congress, and signed the Articles of Confederation as a New York delegate to the Continental Congress. Among the most vocal participants of the 1787 Constitutional Convention, Morris argued for granting Congress veto powers over state laws, direct election of the president and proportional representation in Congress based on taxation. Morris served as American minister to France from 1792-94, and as a New York senator from 1800-03. He later helped form the New-York Historical Society and was the founding chairman of the Erie Canal Commission.

Recall.
When you actively recall a piece of knowledge, you are engaging your memory. Consolidating knowledge in your long-term memory is considerably more effectively accomplished through active recall than by recognition or passive review. It's the quickest and most efficient approach to preparing for tests that need factual knowledge or problem-solving.
Additionally, it is more efficient than other methods of learning, such as taking notes and concept mapping (although these can also be useful study techniques). The truth is that you can only truly grasp and know anything when you can thoroughly recall it from memory. Active recall would be that.
