Answer:
b) the Pacific plate has carried the volcanoes away from the hot spot that formed them
Explanation:
The Hawaiian islands all have volcanic origin. Some are not active, while some still are. All of these islands have been active volcanoes at one point of time, and they have been created by a hot spot that lies beneath the Pacific plate. The hot spot has such a power that it actually manages to break through the central part of the plate where its crust is the strongest and densest. As the magma manages to come out above the water, it manages to create volcanic islands. The Pacific plate though is moving, it is not static, so it drags the volcanic islands away from the hot spot, causing their extinguishing. As those islands are moved away, the hot spot creates new volcanic islands, and the process constantly continuous, resulting in a volcanic island chain.

Answer:
Russia
Only over 7% of the land is fertile
Answer:
Ocean currents, air currents, rotation of the earth.
Explanation:
ocean currents can effect the temperature of the water. air currents can bring in dry warm air, like over Africa and help warm the sea more, or cooler air from the arctic to help cool the surface water. Many of these effect are driven by the Coriolis Effect.
Drought and desertification are closely related phenomena. Persisting over months or years, drought can affect large areas and may have serious environmental, social and economic impacts. While drought is a natural phenomenon, whose impacts can be exacerbated by human activities that are not adapted to the local climate, land degradation is the process of turning fertile land into less or non-productive land. In extreme cases in drylands this is called desertification. Land degradation and desertification are complex phenomena driven by un-adapted human activity in combination with land and climatic constraints. Inappropriate land use, such as monocultures, and unsustainable land management practices, such as deforestation, unsuitable agricultural practices and overexploitation of water resources), can cause land degradation that can be further aggravated by drought.
