UV=13
UW=2y-9
WV=y-5
UV=UW+WV
UV=(2y-9)+(y-5)=2y-9+y-5=3y-14
13=3y-14
27=3y
y=27/3=9
Solution is A, y=9
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.
Answer:One of the most harmful effects of inversions is that they trap the pollution close to the ground, trapping the smog. When there is a temperature inversion, the affect is just the opposite. If the inversion is strong enough, it can cause far off objects to look like they are floating above the ground.
