Which of the following increase the rate of percolation of rain water into the soil?

  1. Constructing check dams

  2. Vegetation and trees

  3. Overgrazing

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Check dams are specifically designed to slow down the flow of runoff, which increases the time water spends on the soil surface, thereby significantly increasing the rate of percolation into the groundwater.

Rain water harvesting is a method employed to:

  1. stop soil erosion

  2. raise the water table

  3. increase afforestation

  4. decrease floods and droughts

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Rainwater harvesting is the accumulation and storage of rainwater for reuse on-site, rather than allowing it to run off. All the water was collected into a well and helps in raising water table.

Multiple choice evs water: a precious resource importance of water let's play with water water and its properties water resources and conservation

Treated water is:

  1. distilled water

  2. potable water

  3. rain water

  4. river water
Reveal answer Fill a bubble to check yourself
A,B Correct answer
Explanation
Treated water is the one that has improved quality of water to make it more acceptable for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.
Distilled water is obtained after condensation of steam.
Potable water is the fittest form of water, suitable for consumption after treatment.
Rain water and river water contains dissolved gases, minerals and particulates from the environment. They are natural form of water.
Therefore option A and B are correct.

Water, ice and steam are all:

  1. elements

  2. mixtures

  3. compounds

  4. none of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Compounds can exist in all three states(solid, liquid, gas) provided that they can be heated/cooled enough(to their respective boiling/melting points). Thus water, ice, and steam all are compounds of hydrogen and oxygen.

Levelling effect is mimimum in

  1. Water

  2. DMSO

  3. Acetic acid

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

The levelling effect refers to the inability of a solvent to distinguish between the strengths of strong acids or bases. Water is a leveling solvent for strong acids; however, the question asks where it is minimum. In non-leveling or differentiating solvents, the effect is minimized.
