FAQs on Infographics: Sources of water - Social Studies for Class 4

1. What are the main sources of water?
Ans. The main sources of water include rivers, lakes, ponds, groundwater, and rainwater. Rivers and lakes provide surface water, while groundwater is found underground in aquifers. Rainwater is collected during rainfall and can be stored for future use.
2. Why is rainwater important as a source of water?
Ans. Rainwater is important because it is a natural source of fresh water. It replenishes rivers, lakes, and groundwater supplies. Harvesting rainwater can also help reduce flooding and water scarcity in dry areas.
3. How can we conserve water from these sources?
Ans. We can conserve water by using it wisely, fixing leaks, taking shorter showers, and using water-efficient appliances. Additionally, we can collect rainwater and use it for gardening or cleaning to reduce dependence on other sources.
4. What role do rivers play in the water cycle?
Ans. Rivers play a crucial role in the water cycle by transporting water from one place to another. They carry water from precipitation to lakes and oceans, where it can evaporate and return to the atmosphere, continuing the cycle.
5. How does groundwater get replenished?
Ans. Groundwater gets replenished through a process called infiltration, where rainwater seeps into the ground and fills the spaces in soil and rocks. This process is essential for maintaining the water supply in aquifers.
