3. Explain how groundwater is recharged Write the names of the factors responsible for
the depletion of the water table.
Answers
Answer:
(i) Increased population : Demand for water has been increased by the increased population. As the number of humans increases, the consumption of water also increases.
(ii) Increasing industries : All industries need water. As the number of human population increase, the number of industries is also increased which definitely increases the consumption of water.
(iii) Lack of water conservation techniques : Main source of water on earth and for the underground water is rain. The water of the rain, if conserved can increase the groundwater level. But this is not due to lack of water conservative techniques.
(iv) Agricultural activities : India is a country which depends on agriculture. The land used for cultivation has increased. So, the consumption of water for agriculture has increased. Irregular rainfall has increased the consumption of groundwater. This has increased the depletion of groundwater.
