FAQs on Water Table - Water : A Precious Resource - CBSE Class 7 Science Video Lecture
| 1. What is the water table? |  |
Ans. The water table refers to the underground level at which the soil and rock are completely saturated with water. It is the upper surface of the groundwater and varies in depth depending on factors like climate, geology, and human activity.
| 2. Why is water considered a precious resource? | |
Ans. Water is considered a precious resource because it is essential for all forms of life. It is used for drinking, cooking, sanitation, agriculture, industry, and various other purposes. However, water scarcity is becoming a global concern due to factors like overuse, pollution, and climate change, making its conservation crucial.
| 3. How does the water table affect groundwater availability? | |
Ans. The water table plays a crucial role in determining the availability of groundwater. When the water table is high, there is abundant groundwater available for extraction through wells and springs. However, if the water table drops due to excessive pumping or drought, it can lead to a decrease in available groundwater.
| 4. What are the factors that influence the water table level? | |
Ans. Several factors influence the water table level, including rainfall patterns, geological formations, vegetation cover, soil type, and human activities. Areas with high rainfall and permeable soil tend to have higher water table levels, while arid regions or areas with impermeable rocks may have lower water tables.
| 5. How can we contribute to the conservation of the water table? | |
Ans. There are several ways in which we can contribute to the conservation of the water table. These include practicing water conservation at home by fixing leaks, using water-efficient appliances, and being mindful of water usage. Additionally, reducing pollution, protecting natural water sources, and promoting sustainable agricultural practices can also help in preserving the water table.
