Water Exercise question Solutions :
Question no – (1)
Answer :
Barren soil on steep slopes gets washed away by heavy rainfall but soil loss can be reduced by soil conditioning and mulches. Soil rich in organic matter can soak water rapidly and preserve moisture content, which helps in reducing the quantity that are lost to erosion. We could plant saplings and smaller shrubs on the slope of the garden. In order to detain the flow of soil, rocks should be placed on the side of the slope . The garden should be watered in a gentle manner. Watering the garden in a forcible manner can increase the rate of soil erosion.
Question no – (2)
Answer :
The roads and footpaths should be constructed in a slanting manner , so that the rainwater could move to the sides and fall beneath the road through the drainage opening. There would be difficulty for rainwater to percolate into the soil, if the entire road are made of concrete .So in order to overcome this problem, some adjacent parts of roads and footpaths should not be made of concrete, which will allow the rainfall to percolate inside.
Question no – (3)
Answer :
(b) Several different methods are adopted in order to make rainwater percolate into the soil. There can be construction of huge dams. But this may not be feasible everywhere. In such circumstances, the government and the people works collectively by undertaking several tasks such as constructing smaller reservoirs, contour bunding, bunds are also constructed in order to stop the water of the smaller streams. In some places, there also digging of wells in river beds which will allow water to collect in them. Rainwater that falls on the roofs of the house are also stored in large tanks. All such methods will help us in storing adequate amount of water. It is extremely essential to use water conservatively, to stop the wastage of rainwater from flowing off and to make it percolate into the ground or to reserve it in tanks.
(c) It is essential to stop rainwater because by stopping rainwater that is flowing away and by allowing it to seep into the soil or reserving it, it will result in availability of water which can be used even after the rainy season. The percolation of rainwater into the soil will lead to increase in the ground water level. Tress and agriculture can also get sufficient amount of water by this procedure. This method will result in more land cultivation and the water level will also rise. In this way, drought condition can be averted.
(c) Taking steps in order to assure that there are availability of rainwater even after the period of rainy season is known as water management. Storing rain water in tanks and making rainwater percolate into the soil are some of the methods of water management.
Question no – (4)
Answer :
(a) We get rainwater throughout the year
This statement is not True.
Rain continuously brings us water but we experience rainfall only for a duration of four months. If there is no storage of rainwater, then we will not have water for our daily requirements after the period of rainy season. So in order to meet the whole year’s requirements of water, it is necessary to stop the rainwater.
(b) During a famine, the government moves people and animals temporarily to safe places.
This statement is absolutely True.
During a condition of famine, the government transiently moves people and animals to safer places where they can be provided with the basic requirements for their sustenance. Fodder camps are also organized to provide care to the domestic animals.
