Solution :
The type of melting that is responsible for the mafic magmas for the following plate tectonic settings :
a). Mid - ocean ridges
At the mid oceanic ridges, the two plates diverges away and the new oceanic crust is formed by the effusion of the magma. The earth's interior is exposed as the two plates are moved away.
b). Continental rift :
A new oceanic crust is formed by the effusion of the magma and the two plates diverges away. Thus it causes the formation of the melt in the continental drift. As a result, the crustal thickness decreases.
c). Oceanic and continental volcanic arc :
The oceanic arc and the volcanic arc are the locations of the convergence. The denser plate of the arcs subducts under the less denser plates or the lighter plates and it moves downwards into the mantle, which causes the increase in temperature of the surroundings.

Answer:
1. earliest Civilizations began on this continent - Africa
2. continent which has the Amazon River - South America
3. continent surrounding the South Pole - Antarctica
4. areas with warmer climates - low latitudes
5. continent in the Eastern Hemisphere which has mostly young nations - Asia
6. small continent in the Southern and Eastern Hemispheres - Australia
7. the poles are in these - High Latitudes
Explanation:
First civilization as we know are created in Africa and later spread to Asia and Europe.
Amazon flows through South America, with its largest part through Brazil.
Antarctica is the the continent on the South, that totally surrounds the South Pole.
Of course, all the area on the low latitudes usually have warmer climate, such as central Africa or Asia.
Median age in Asia is around 32 years.
Australia is the smallest continent.
High latitudes includes areas around North and South Pole.
Extremely hot, forms in mantle, known as lava in surface, contains dissolved gasses
