Over Use of Groundwater - it’s Consequences — Flashcards

Answer

Groundwater is water present in deeper layers of soil. It is recharged mainly through percolation of rainwater into the soil.

Answer

Groundwater is under serious threat because it is being overused faster than it is naturally recharged. When water use is greater than percolation, the level keeps falling.

Answer

Recharge of groundwater means water from rain moves downward through the soil and refills the underground water store. This natural process helps maintain groundwater levels.

Answer

Rainwater percolates into the deeper layers of the soil and becomes a source of clean and pure water for human use. This is why rainwater recharge is very important.

Answer

Bore wells need to be dug deeper every year because water use per year is more than the amount of water that percolates into the ground. As a result, the water table goes down.

Answer

More than 300 districts have reported a groundwater level decline of over four metres during the past two decades.

Answer

It means groundwater is being used at a very high rate across a large part of the country, more than nature can replace it through recharge. This shows that the problem is widespread.

Answer

Domestic, agricultural, and industrial uses of water are increasing day by day.
