Questions and Answers for CBSE Class 10 Social Science Geography Chapter "Water Resources"
- Q1: Why is water considered a valuable resource?
ANS: Water is considered a valuable resource because it is essential for all forms of life, supports ecosystems, and is a key component for various human activities. - Q2: What is water scarcity and what causes it?
ANS: Water scarcity is the lack of sufficient available water resources to meet the demands of water usage within a region. It can be caused by factors like overuse, pollution, and inefficient management. - Q3: How does rainwater harvesting help in water conservation?
ANS: Rainwater harvesting helps in water conservation by collecting and storing rainwater for later use, reducing dependence on groundwater, and mitigating the effects of drought. - Q4: What are the impacts of large dams?
ANS: Large dams can provide irrigation, hydroelectric power, and flood control, but they can also lead to environmental damage, displacement of people, and disruption of aquatic ecosystems. - Q5: What role do forests play in maintaining the water cycle?
ANS: Forests play a crucial role in maintaining the water cycle by facilitating the infiltration of rainwater into the soil, which replenishes groundwater and ensures a continuous water supply. - Q6: How can individuals contribute to water conservation?
ANS: Individuals can contribute to water conservation by using water efficiently, fixing leaks, installing water-saving devices, and spreading awareness about the importance of water conservation. - Q7: What is watershed management?
ANS: Watershed management involves the conservation, regeneration, and judicious use of natural resources within a watershed to ensure sustainable water flow and reduce soil erosion. - Q8: Why is it important to manage water resources sustainably?
ANS: Sustainable water resource management is vital to ensure that current and future generations have access to clean water and to protect the health of the environment. - Q9: What are some traditional methods of water conservation in India?
ANS: Traditional methods of water conservation in India include the use of johads (small earthen check dams), bawris (stepwells), kunds (tankas), and khadins (agricultural fields with embankments).
