Which of the following environmental impacts is not associated with coal consumption? A) In strip mining, the overlying soil and rock layers are removed so that coal veins can be found.
B) Substances that can react with atmospheric substances to form acid rain are released into the
air.
C) Toxic heavy metals such as mercury are released into the environment.
D) Waste products from coal consumption must be stored safely for thousands of years.

D) Waste products from coal consumption must be stored safely for thousands of years.

Explanation: Both A and B are wrong, and this answer seems to relate more with how to deal with the waste products rather than their direct environmental impacts. If it isn't D, then it must be C, although the U.S. EPA states that coal consumption can release mercury into the atmosphere.

Hope this is somewhat helpful :)

like many students at university, you may be unhappy about the results you attain in exams. you may feel that even with all you are doing there must be something more -- or different-- you could be doing to get better grades. we have all at some time or other heard of that student who only studies a couple of hours for final exams and scores a's every time. we stand in awe of those who seem to breeze through without undue effort and seem to need very little in the way of studying to nail an exam. the reasons for success, in what i think are the vast majority of cases, are less esoteric than many students think: successful students consistently apply a series of productive strategies with view to attaining clearly identified learning and grade goals throughout the academic term.
