Which of the following is mostly used as a drinking water source by us?

  1. Sea water

  2. Glaciers

  3. Ground water

  4. None of these

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

Groundwater is mostly used as drinking water source by us. 

Sea-water contains dissolved salt in it, hence it is not generally used for drinking purposes unless purified. 
Hence, the answer is C.

Multiple choice social science water: a precious resource sources of water and water cycle groundwater and depletion of water table water table the water cycle

A depletion in the water table of a place is caused by which of the following?

  1. Constructing factories and houses

  2. Making concrete roads and floors

  3. Deforestation

  4. All of these

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

Constructing factories and houses involve a large scale of deforestation. Due to deforestation, the soil will not remain intact due to which the water holding capacity of the soil decreases which causes a depletion in the water table. Making of concrete floors and roads do not allow the rainwater to seep through the soil and therefore causes a fall in the level of the water table.


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

Well water is an example of:

  1. surface water

  2. rain water

  3. underground water

  4. river water

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

Well water is an example of underground water. A water well is an excavation or structure created in the ground by digging, driving and or drilling to access ground water in underground aquifers. The well water is drawn by a pump or using containers such as buckets that are raised mechanically or by hand.

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.
