Q.1.Explain the factors responsible for the depletion of water table.
Q.2.You have been asked to maintain a garden. How will you minimize the use of water?
Q.3. Explain how groundwater is recharged.
Answers
1.The factors responsible for the depletion of water table are as follows: 1)Increasing population - As a result of increasing population, all the facilities such as houses, shops, roads, offices, pavements, etc. ... 2) Increasing industries - Most of the stages of manufacturing processes in industries require water.
2.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.
3.Groundwater is recharged naturally by rain and snow melt and to a smaller extent by surface water (rivers and lakes). ... Recharge can help move excess salts that accumulate in the root zone to deeper soil layers, or into the groundwater system. Tree roots increase water saturation into groundwater reducing water runoff.
Answer:
the factors responsible for the depletion of water table are
Increasing population
Increasing industries
Underground water is recharged by rain and snow melting to a smaller extent by surface water.
