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:
Answer
A
Explanation
As per NASA, over the last 50 years, Aral Sea has shrunk by about 75% of its original size mainly because of water diversion for agricultural usages. Its depth fell from 68 meters in the 1960s to less than 10 meters. Lake Baikal shows more of a fluctuating regime and shrinkage is not comparable to that of Aral Sea. Black Sea has not shrunk immensely due to human activities.
