3. How can you say that the plants play an important role in adding water vapour into the atmosphere?
Water vapour can also be transferred into the atmosphere with the help of plants. Water is necessary for the growth of plants. These plants take water from the soil. Some water is used by the plants to prepare food. Also, this water is retained by different parts of the plant-like fruits, roots, flowers, stem and leaves. Therefore, a part of the water is released into the air by the leaves through the process of transpiration. In this process, a large amount of water vapour goes into the air.
4. Explain the water cycle in detail.
The sun helps in heating the water. The water gets evaporated from the sources like ponds, seas, rivers and oceans. As water vapour is lighter than air, it gets carried away by air. At some height, the water vapour gets cooled and gets converted into water droplets. Water droplets combine together to form a cloud. When these clouds come close and collide with each other, water falls in the form of rain and get collected in seas, oceans, rivers and ponds. This process is known as the water cycle.
5. What do you understand about rainwater harvesting? Also, list some advantages of rainwater harvesting.
The process of collecting and storing rainwater that runs off rooftops, roads, parks, etc. is known as rainwater harvesting. This water gets stored or recharged into the groundwater.
Some advantages of rainwater harvesting are:
This method is acquired in areas where there is less rainfall.
It helps in increasing the level of groundwater.
It assists in reducing the effect of drought.
This technique is crucial in those areas where there are no rivers or lakes and people rely on groundwater.
Reduce water and soil pollution.
