Answers
1:We cannot live without water. Saving water helps to preserve our environment. It reduces the energy required to process and deliver water, which helps in reducing pollution and in conserving fuel resources. Saving water now means having water available in the future for recreational purposes, too.
2:Broadly there are two ways of harvesting rainwater, namely; surface runoff harvesting and rooftop rainwater harvesting. Rainwater harvesting is the collection and storage of rain for reuse on-site, rather than allowing it to run off. The stored water is used for various purposes, such as gardening, irrigation, etc.
3:the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.
hope this helps u
Answer:
a] We conserve the water as there should be enough water for the future when there is no rain and there is scarcity of water
b] 1} By letting the water absorbed by the soil and then later it be used as ground-water
2}By digging the pits to water be collected in it or n tanks or dams
c] Water cycle is the process where the water in water bodies gets evaporated and then it is in the form of vapour then it condenses and forms clouds and then the water comes back in the form of rain in the water bodies and the cycle goes on
