As more water is taken from an aquifer than is replaced, what happens to the aquifer? a. the rivers fully recharge the aquifer with fresh water supply. b. the water company decreases the amount of water each household is allotted. c. the pipes draw recycled water up to the surface where it is stored in wells. d. the water level of the aquifer drops as a result of a drawdown.

The correct answer is - d. The water level of the aquifer drops as a result of a drawdown.

The aquifers are extensively used around the world in the past century. The reason for the usage of these waters is that they are of good quality, the surface waters are lacing in certain places and lot of them are polluted, they are used for drinking, for the households and companies, for agriculture.

Such large usage of the aquifers results in much more water being extracted from them, than what naturally it is recharged. Because of this, the level of the water in the aquifer is constantly going down, leading to its total drying out eventually.

Explanation:

in the united states, the president is controlled by the

constitution, and in all respects subordinate to it. insofar

as it deals with presidential power, however, the american

constitution has proved to be a highly malleable document.

with very few exceptions,' the constitutional provisions relating to the president have not been changed at all since

they were ratified in 1787. but in the late twentieth century, those provisions do not mean what they meant in

1787. the constitution is a legal document, and it is enforced judicially; but its meaning was hardly fixed when it

was ratified. in particular, the contemporary president has

far broader powers than the original constitution contemplated. it is remarkable but true that large-scale changes in

the authority of the president have been brought about

without changes in the constitutional text, but nevertheless

without significant illegality.

this is a paradox. is it not clear that constitutional

changes, if not textual, are illegal? the paradox has considerable relevance to our current thinking about the presidency in particular and about constitutionalism in general.

perhaps the framers of the american constitution feared

legislative power most of all; 2 but from well-known events

in the twentieth century, it is possible to conclude that it is

presidential power that holds out the greatest risks to both

liberty and democracy. the president is by far the most visible leader in the nation; he is often the only person in government with a national constituency. moreover, he is
