By the end of the year, German troops had advanced almost 1,000 miles to the outskirts of Moscow. Soon after the invasion, mobile killing units began the mass murder of Soviet Jews. German military and civilian occupation policies led to the deaths of millions of Soviet prisoners of war and Soviet civilians.
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.

Cardinal directions or cardinal points are N W S and E. Intercardinal directions or points are NE SE SW and NW. We also have eight secondary intercardinal directions for a more detailed location on the compass rose.
Consistency defines the extent to which you believe that the person being observed behaves in a similar fashion when confronted on other occasions with the same or similar situations. A consistent theory is one that does not lead to a logical contradiction in classical deductive logic. The absence of contradiction might be expressed in semantic or syntactic terms.
According to the semantic definition, a theory is consistent if it has a model, that is, if there is an interpretation under which all formulas in the theory are true. A consistency proof is a mathematical demonstration that a specific theory is consistent. The incompleteness theorems had a significant impact on Hilbert's program.
