Question

In dry environments, farmers often dig wells to provide irrigation for their crops. Which of the following is an environmental risk associated with using wells to pump large amounts of water out of the ground?

Answer 1

There are no choices available, however, the possible environmental risk that this situation can give is the depletion of ground water. The amount of water being pumped out from the ground will take time to replenish, hence emptying ground water and possibly mixing sediments trapped inside the cavern of water. This situation can eventually contaminate new ground water that will seep in into the cracks that were dug for irrigation.

Answer 2

Answer:

Here are the choices...

A.  The climate in the area could be considerably altered by the decrease in groundwater.

 B.  The local water table could be lowered, causing many local plants to die.

 C.  The water cycle would come to a halt in the surrounding areas.

 D.  The irrigated crops could develop root rot or other fungal diseases.
