Question

Which of the following causes a decrease in the water table?

• A. Lack of rain water harvesting infrastructure.
• B. Drip irrigation
• C. Cloud seeding
• D. Growing trees

Answer 1

The correct option is A Lack of rain water harvesting infrastructure.

Lack of rain water harvesting infrastructure reduces the amount that enters the ground. Hence, it lowers the water table.

Cloud seeding promotes rain in a region and helps in restoration. Growing trees holds soil and water and attracts rain. This increases the water level in a region. Drip irrigation in agriculture ensures that water is delivered close to the roots and more water seeps into the ground.
