Here are some of the environmental challenges that Africa is facing at the moment:
1. desertification: larger patches of African land are turning into deserts, which is obviously a huge problem because the vegetation of the continent is changing and disappearing
2. no access to water: many African nations have problems finding water in this arid country, which is a danger to their lives
3. population explosion: there are more and more Africans born, and there are not enough resources to sustain them all
Umm ;-; I don’t understand your question
Answer:
A middle-class town (houses, a school)
Explanation:
The appropriate answer is B. Chains of volcanoes along ocean coastlines. The theory of plate tectonics states that the earth's crust is divided into plates that float on the semi-molten mantle below. Plates can converge, diverge or slide past each other. Chains of volcanoes along coastlines are evidence of plates converging with one plate subducting beneath the other. The subducting plate will melt producing magma which is lighter than surrounding rock and so will force its way through cracks and fissures in the surface. Once magma reaches the earth's surface, volcanoes are formed.
