term impact on the water table?
4. You have been asked to maintain a garden. How will you minimise the
use of water?
5. Explain the factors responsible for the depletion of water table.​

Answer 1

Answer:

2. Recharging of groundwater takes place by the rainwater and water present in the water source like river and ponds. The water tends to seep through the soil and fill the empty spaces and cracks below the ground. That's how groundwater gets recharged.

3.There are ten tubewells in a lane of fifty houses. What could be the long term impact on the water table? Answer: Ten tube-wells in a lane of fifty houses can lead people to mindlessly exploit the groundwater. This can lead to depletion of the water table in the long run.

4.To maintain a garden, water is necessary. Therefore, to minimise the use of water, we can apply the drip irrigation method. In this method, water is supplied directly to the base of the plants using narrow pipes, thereby reducing the loss of water.

5.Various factors responsible for the depletion of water table are: ... As the number of human population increase, the number of industries are also increased which definitely increases the consumption of water. 3) Lack of water conservation techniques: Main source of water on earth and for the underground water is rain.
