The statement which is true is that, "Whereas the Southwest region in U.S. generally has extremely high water resource vulnerability, acid rain is a major issue on the East Coast."
What do you mean by water resource vulnerability?
The water resource vulnerability is defined as the tendency of water resource systems to break down because of the external influences. Vulnerability of water resources includes two aspects- sensitivity and adaptability of water resource systems to external driving factors.
The water resource vulnerability includes vulnerability of water quality and quantity. Thus, because of the climate change and human activities, human society is facing water resources shortage, frequent natural calamities, and a series of problems which leads to the increase in the vulnerability of water resource systems.
What is acid rain?
Acid rain is a form of precipitation which is unusually acidic, with acidic components such as sulfuric or nitric acid which falls to the ground from the atmosphere in wet or dry forms. This includes- rain, hail, snow, fog, or even dust that is acidic.
Which part of the U.S. is most affected by water resource vulnerability?
The part of the United States which is most affected by water resource vulnerability is the Southwestern region of United States. This region stemmed mainly from consumptive uses whereas the vulnerability in watersheds of the southern US was due to changes in flooding, water quality issues, and other uses.
Which part of the U.S. is most affected by acid rain?
The region of the United States which is most affected and harmed by acid rain is the East Coast, including the Appalachian Mountains and the Northeast Some.
Thus, acid rain occurs naturally, but when sulfur dioxide and nitrogen oxide emissions from smokestacks combine with rain they tend to make sulfuric and nitric acid in amounts which harm the environment.
Hence, option B is correct.
