Answer:
C) homogeneity
Explanation:
All regions possess all of these characteristics, except for homogeneity. Homogeneity is a characteristic that describes a great similarity among the units that compose a region. Moreover, it implies a greater similarity between these internal units than between its units and those of other regions. The aspects analyzed in order to judge these similarities are usually physical (climatic zones, botanic areas, etc.) or social (historical or cultural regions).
Answer:
The main reason so few African leaders are replaced in free elections is because the vast majority of African nations have serious socio-political and economic problems, which generate enormous political instability and serious situations of social tension. Thus, for example, countries like Mali have 75% of their population living on less than 2 dollars a day, while others, like Nigeria, increase this percentage to 92%.
Thus, these situations of poverty, need for primary resources and lack of opportunities generate social conflicts that, translated into politics, are the starting point for revolutions, dictatorships and other anti-democratic manifestations.
The divergent plate boundaries are the places where the tectonic plates move away from each other. As they move part, which is actually driven by the convection currents in the mantle, they leave a gap between them of very thin and cracked crust. The convection currents manage to push the magma up with easy through this gap. As the magma pushes upward, it reaches the ocean floor, where the temperatures is significantly lower and it quickly cools off and forms new igneous rocks, or rather new crust. Since the magma is constantly rising and constantly making new crust, the new crust is pilling up, forming a mid ocean ridge with intense volcanic activity. Eventually, the rising magma will manage to come out on the surface and create volcanic islands, thus a chain of volcanic islands, which can even result in the formation of new large land of mass.
It traps energy from escaping into space!
