Question 27 • CSD Summer 2026 Human Geography

River waters that feed the Aral Sea in Asia were diverted for irrigation. Which of the following events did not result from this?

Answer
A
The Aral Sea is now just 10% of its original size.
B
Extensive desertification has occurred.
C
Fish could no longer survive because of the decreased salinity.
D
The surrounding land was contaminated.

Explanation

Diverting river water caused the Aral Sea to shrink dramatically, exposing seabed and contributing to desertification and contamination of nearby land. As the sea lost water, its salt concentration increased rather than decreased. The increased salinity harmed fish, so the claim that fish could no longer survive because of decreased salinity did not result from the diversion.
