Answer:
Since the 1930s the Middle East has emerged as the world's most important source of energy and the key to the stability of the global economy. This tumultuous region produces today 37% of the world's oil and 18% of its gas. When it comes to reserves, the Persian Gulf is king. --> MIDDLE EAST.
Russia, country that stretches over a vast expanse of eastern Europe and northern Asia. Once the preeminent republic of the Union of Soviet Socialist Republics (U.S.S.R.; commonly known as the Soviet Union), Russia became an independent country after the dissolution of the Soviet Union in December 1991. --> RUSSIA
Explanation:
SUMMARY UPDATED:
The middle east may be emerged as one of the most important source of energy to the world but Russia is one of the biggest places in the world although it is an independent country causing there to be more recourses from Russia compared to Middle East! The only difference here is that Middle East has been important since 1930s but Russia became independent form Soviet Union on 1991.
A small area map, i think.... hoped it helped
Answer:
Geographers spend time comparing conditions in different places and regions of the world in order to compare or differentiate landforms, climates, economies, people and cultures and maybe even resources.
Explanation:
For instance, if you know that all the countries in the different continents were combined as a super continent before continental drift came into being, you would realise that certain countries in South America may have particular features or something similar to those of Australia or any other country. In can either be through the finding of fossils, landforms, etc.

The latitude of the Antarctic Circle is roughly 66.5 degrees South.
There is one point on the Antarctic Circle at every possible longitude.
Answer:
Partial melting occurs when only a portion of solid is melted. It is thus enriched in the chemical components of minerals with lower melting temperatures and the remaining unmelted portion of the rock is composed of minerals with highest melting temperatures. Partial melting preferentially enriches melts with incompatible elements.
Partially melted rock do not usually experience complete melting inside the Earth, due to their different chemical composition and their melting points.
It is thought that partial-melting processes play a major role in generating more-defined liquids from less-evolved ones, so that many basalts may be the result of partial melting in the upper mantle, and many granites may have derived partly or completely from the partial melting of continental crust (anatexis).With increasing temperature and pressure, the subducted oceanic crust (of basic composition) first undergoes metamorphism and then begins to melt or release watery fluids; this material rises into the overlying mantle, which may also begin to melt, giving rise to intermediate magma.
