FAQs on Water Cycle
1. What is Water Cycle?
The water cycle describes the movement of water around the Earth. The sun causes water from rivers and oceans to evaporate and form small water drops in clouds. When the clouds get heavy, rain falls, and the water returns to rivers, lakes, and the land. It's like a giant circle where water rises, forms clouds, and then falls as rain.
2. What are different uses of water
Water is necessary, and we use it for a number of functions:
- Drinking
- Bathing
- Cooking
- Growing Plants
- Playing
- Cleaning
- Making Electricity
3. How does water get into the sky?
Water enters the atmosphere through a process of "evaporation." When the sun shines on water, it converts it into small water vapour particles that rise into the sky and form clouds.
4. What are clouds, and why are they important?
Clouds are puffy masses of water vapour in the sky. They're important because they supply rain. When the clouds get heavy with water, they release rainfall to the ground, allowing plants to flourish and animals to drink.
5. Why is it essential to save water?
Saving water is important because there is a limited amount of fresh water on Earth. We need to use it wisely to ensure there's enough for everyone and to protect our environment.
