Explanation:
So we can use them for further research in the future
Answer:
b. The terrain is mostly desert and mountains
Explanation:
Afghanistan is a country that has proved to be extremely difficult to invade, and that has been the case for thousands of years. There is one major reason for this, the geography of the country. The country is dominated by very high mountains that create rain shadow and and deserts. The mountains themselves are extremely difficult for passing through, and even if they are passed by an invading army, they will take their toll. Once the mountains are passed, an invading army would face desert, very dry climate, very few food sources and very little water, with temperatures varying from scorching hot in the summer, to freezing cold in the winter. So even if an army passes through both of these natural obstacles, when it comes to face the natives it will be too weak to invade.
Answer:
C
Explanation:
just think about it they are Langer in the winter and shorter in the summer
Answer:
Yes, for example humans can make a triangle if they stack up on eachother and have good stability.

Answer:
False.
Explanation:
Regional metamorphism is a common type of metamorphism involving the effects and cooperation of directed pressures and shearing stress as well as a wide range of confining pressures and temperatures. The heat element facilitates recrystallisation; but the stress element not only promotes recrystallisation, but is powerful in deforming the rocks, and producing new structures.
It is related both geographically and genetically to large orogenic belts, and hence is regional in character.
Regional metamorphism does NOT produce nonfoliated metamorphic rocks in the depths of mountain ranges. Regional metamorphism takes place at deeper regions of the crust and is, as the name already signifies, of regional extent. The different types of regional metamorphism, or still dynamothermal metamorphism, are confined to areas of mountain building, so that metamorphism as well as orogenesis ought to be regarded as due to one and the same process.
