Explanation
  • Water scarcity is the lack of fresh water resources to meet water demand. It is mainly due to lack of water or due to a lack of adequate machinery or tools to supply water.
  • The effects of water scarcity can be grouped into these 4 broad categories. They are Health, Hunger, Education, and Poverty.
  • The sign of water scarcity includes the following. They are Dried fields having cracks on them, Nutrient deficient plants and Struggle to obtain water from bore wells.

Water harvesting is done by ____________ processes.

  1. rainwater

  2. groundwater

  3. both A and B

  4. atmospheric water
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Water Harvesting
It means storing rain where it falls or storing the run off in your own village or town. And taking measures to keep that water clean by not allowing polluting activities to take place in our locality.
It can be done by two major processes:
1. Rainwater harvesting
It is a method of collection and storage of rainwater into natural reservoirs or tanks, or the infiltration of surface water into subsurface aquifers.
2. Groundwater harvesting 
Groundwater harvesting is a method to save water placed under the ground to control the groundwater flow in an aquifer, and to raise water table.

Find out the wrong statement from the following:

  1. Water evaporates from plants, animals and oceans

  2. Animals living in the water are not harmed during floods

  3. There is no vegetation during draughts

  4. Water available for use is very limited
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Water evaporates from plants through transpiration and oceans through evaporation. There is no vegetation during draughts as there is no availability or very little presence of water in the ground making the area dry and cracks the ground.

Water available for use is very limited as most of the water present in the earth's surface is saline.

Rain water harvesting is a method employed to:

  1. stop soil erosion in a place

  2. raise the water table of a place

  3. increase afforestation around a place

  4. decrease floods and droughts in a place
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Rain water harvesting is a method employed to raise the water table of the plane. Its is a single method by which rainfall is collected for future usage. The collected rainwater may be stored, utilized in different ways or directly used for recharge purposes. It is the accumulation and storage of rainwater for re-use on site, rather than allowing it to run-off.

  2. Storage units

  3. Conveyance mechanism which transports the water falling

  4. Sloping roof
Reveal answer Fill a bubble to check yourself
A,B,C,D Correct answer
Explanation
Catchment areas: roof surface to collect the rain.
Conveyance: channels or pipes from roof or catchment area to storage.
Storage tanks: : cisterns or tanks where collected rainwater is securely stored  i.e. insect proof.
Sloping roof is falls in the category of catchment areas.

The method of rainwater harvesting which can be adopted by individual house owners is:

  1. construction of recharge trenches

  2. on channel storage of water

  3. creation of new water bodies

  4. roof-top rainwater harvesting
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Harvesting rain water from roof tops is an easy and eco- friendly method of augmenting house hold level water availability. Roof top rain water harvesting involves diverting and recharging or storing part of rain water that falls on the roof of a house.

To prevent excess use of water from taps and tanks, we can collect water from :

  1. rain

  2. streams

  3. rivers

  4. sea
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

To prevent excess use of water from taps and tanks, we can collect water from rain.

Because if we use the rain water by the help of rainwater harvesting technique the excess uses of water from tanks and taps which is supplied by government can be prevented.

Multiple choice chemistry water in our life how can we conserve water? droughts, floods and water conservation conservation of water and its importance and methods

If the irrigation water contains dissolved salts, _____________ is particularly suitable.

  1. surface irrigation

  2. drip irrigation

  3. sprinkler irrigation

  4. localized irrigation
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Drip irrigation is a type of micro-irrigation system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants either from above the soil surface (or) buried below the surface. The goal is to place water directly into the root zone, minimize evaporation to reduce the wastage of minerals.


Thus, drip irrigation is suitable for the irrigation water which contains dissolved salts.

Hence, the correct option is $\text{B}$

_____________ is a technique of watering plants by making use of narrow tubings which deliver water directly at the base of the plant.

  1. Sprinkler irrigation

  2. Drip irrigation

  3. Center pivot irrigation

  4. Localized irrigation
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Drip irrigation is a method of irrigation in which water is dripped slowly to the roots of the plants through narrow tubes. This method allows water to be delivered directly to the base of the plants. This method conserves water.
Drip irrigation is also known as a localized irrigation.
Sprinkler irrigation supply water in the same manner as supplied by the rainfall. Here water is distributed through the system of pipes and then it is sprayed on the areas through sprinklers.
In center pivot irrigation, the equipment rotates around the pivot and water is supplied through sprinklers.

Which of the following is traditional way to conserve water?

  1. Tube-well

  2. Bawris

  3. Rainwater harvesting

  4. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Bawris are one of the old methods of rain water management. These are deep wells dug in the ground which have steps to reach the water stored. These bawris help in storage of water for longer time as the amount of evaporation of water from the deep well is very less.Bawris are very popular in Rajasthan. People of Rajasthan get access to water through bawris even in summer season.

Which of the following can reduce flood risk?

  1. Building regulations

  2. Dams and detention basins

  3. Awareness programme

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Flood risk in new developments can be reduced by restricting the location of development (zonings) and placing controls (regulations) on development. In existing developed areas, risk can be reduced by modifying flood behaviour (for example, through dams, detention basins, levees, waterway modifications), property modification measures (for example, land filling, flood proofing, house raising, removing developments), and response modification measures (for example, upgrading flood evacuation routes, flood warnings, flood evacuation planning, flood education programs).
