FAQs on All About Water Video Lecture - EVS Class 5

1. What is the importance of water for living beings?

Ans. Water is essential for all forms of life. It helps in various biological processes such as digestion, respiration, and circulation. Water regulates body temperature and acts as a solvent for nutrients, allowing them to be transported in the body. Additionally, many organisms depend on water for their habitat, making it crucial for ecosystems.

2. How is water distributed on Earth?

Ans. Water covers about 71% of the Earth's surface. The distribution is primarily in the form of oceans, which hold about 97% of the Earth's water. Freshwater, which is necessary for drinking and irrigation, accounts for only about 3% of total water, with the majority found in glaciers and ice caps, while rivers, lakes, and groundwater contain the rest.

3. What are the different states of water?

Ans. Water exists in three states: solid (ice), liquid (water), and gas (water vapor). The state of water changes depending on temperature and pressure. When frozen, water becomes solid ice, while heating it turns it into vapor. These transitions are important in the water cycle, where water evaporates, condenses, and precipitates back to the Earth.

4. What is the water cycle and why is it important?

Ans. The water cycle is the continuous movement of water within the Earth and atmosphere. It involves processes like evaporation, condensation, precipitation, and runoff. This cycle is important because it distributes fresh water across the planet, replenishes water sources, supports ecosystems, and regulates climate.

5. How can we conserve water effectively?

Ans. Water conservation can be achieved through various methods such as fixing leaks, using water-efficient appliances, collecting rainwater, and practicing mindful usage. Simple actions, like turning off the tap while brushing teeth or taking shorter showers, can significantly reduce water waste and help preserve this precious resource.
