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.

Answer:
Dry and barren land becomes desert.
Explanation:
Desertification is a process when the desert expands at the expense of an area that was not a desert. Basically, an area that was a steppe, for example, because of mismanagement or climate changes, can gradually become a desert as it gets drier and the land barren, so the desert will replace it.
In Africa, desertification is a big problem. Both, human mismanagement of soil and climate change have resulted in damaging the biomes that are close to the deserts, mainly the steppes. The soil is often left without nutrients so it can not support vegetation, which in turn also affects the water sources and precipitation paterns in a negative manner. The land becomes barren and drier than it was, and being close to the desert, the winds quickly manage to cover the surface with sand, converting it into a desert.
