Section B – Short Answer Questions (2 × 10 = 20 Marks)
Q11. Why is water considered a renewable but limited resource?
Answer:
Water is considered a renewable resource because it is continuously replenished through the hydrological cycle involving evaporation, condensation, and precipitation. However, it is limited because the amount of usable freshwater is fixed and unevenly distributed. Overexploitation, pollution, and climate change further reduce its availability, making water conservation essential.
Q12. Mention two causes of water scarcity in India.
Answer:
Two major causes of water scarcity in India are rapid population growth leading to increased demand and over-extraction of groundwater for agriculture and industries. Uneven rainfall and poor water management further aggravate the problem.
Q13. How does over-irrigation lead to waterlogging?
Answer:
Over-irrigation supplies excess water to agricultural fields, causing the water table to rise. When soil pores become saturated, air circulation is reduced, leading to waterlogging. This adversely affects crop growth and soil fertility.
Q14. What is the role of dams in flood control?
Answer:
Dams help control floods by regulating river flow. During heavy rainfall, excess water is stored in reservoirs and released gradually, reducing the risk of floods downstream and protecting life and property.
Q15. Name two advantages of rainwater harvesting.
Answer:
Rainwater harvesting helps recharge groundwater levels and reduces dependence on external water sources. It also minimises surface runoff and prevents flooding and soil erosion.
Q16. What is meant by surface water?
Answer:
Surface water refers to water found on the Earth’s surface in rivers, lakes, ponds, reservoirs, and streams. It is a primary source of water for irrigation, domestic use, and industries.
Q17. How does industrialisation increase water demand?
Answer:
Industrialisation increases water demand as industries require large quantities of water for manufacturing processes, cooling, cleaning, and waste disposal. Rapid industrial growth puts pressure on local water resources.
Q18. Mention two disadvantages of multipurpose river projects.
Answer:
Multipurpose river projects often lead to large-scale displacement of people and submergence of fertile land and forests. They also disturb natural river ecosystems and aquatic life.
Q19. Why is groundwater depletion a serious concern?
Answer:
Groundwater depletion lowers the water table, making wells dry and increasing the cost of extraction. It leads to land subsidence, reduced agricultural productivity, and long-term water insecurity.
Q20. How can water pollution affect human health?
