UPSC PYQ
5. Which of the following has/have shrunk immensely/dried up in the recent past due to human activities?
1. Aral Sea
2. Black Sea
3. Lake Baikal

Select the correct answer using the code given below:

A. 1 only
B. 2 and 3
C. 2 only
D. 1 and 3

Answer: A
Explanation

  • According to NASA, water diversion for agricultural use in the surrounding areas is the main reason why the Aral Sea has shrunk by around 75% of its original size during the past 50 years. It is now less than 10 metres deep, down from 68 metres in the 1960s.
  • Since 1962, the water level in Lake Baikal has fallen 11 times below the crucial level of 456 metres.
  • Consequently, while Lake Baikal exhibits more of a changing regime and shrinkage is not similar to that of Aral
    Sea, the Aral Sea has drastically dried up.
