Water is a very important natural resource. Lakhs of residents living at various locations do not have proper water supply. It is the responsibility of government to provide portable water to the residents in each and every state. In doing so the government should take othentic measures to save the ground water from being polluted. The state government should install the water purifiers to purify water before supplying it to the residents.

  1. Pottable, Othantic

  2. Portable, Authantic

  3. Potable, Authentic

  4. Poteable, Athentick

  5. None of these

The correct spellings are potable and authentic.

Multiple choice

Water from an artesian well flows up automatically due to

  1. heavy rainfall in the region

  2. volcanic activity

  3. hydrostatic pressure

  4. geothermal energy
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Artesian wells occur when water is confined between impermeable rock layers under pressure. When a well is drilled into this confined aquifer, the hydrostatic pressure forces water upward without pumping. The pressure comes from the water table at a higher elevation in the recharge area of the aquifer.

Multiple choice

What is an aquifer?

  1. A hole dug underground

  2. The space between the rocks below the water table

  3. The pores in the leaves for transpiration

  4. A pump to pump out the underground water

  5. A place built to store water in the village

B Correct answer
Explanation

Yes, the space in between layers of hard rocks is called an aquifer. An aquifer is an underground layer of water-bearing permeable rock or unconsolidated materials (gravel, sand, or silt) from which groundwater can be extracted using a water well.

Multiple choice

Which of the following has no role in managing water?

  1. Rain water harvesting

  2. Constructing dam

  3. Drip irrigation

  4. Industrial boom

  5. Repairing the leaking taps
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Yes, it is correct as increase in the number of industries means increase in the use of water and less underground water recharging. Repairing of leaking taps saves water loss. Hence, manages water.

Multiple choice

What does recharging the ground water means?

  1. To pump underground water out

  2. To conserve underground water

  3. To use underground water

  4. To clean the ground water

  5. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Yes, it is correct. The term recharging the ground water means, conserving the ground water, allowing the rain water and excess of waste water to seep into the ground. This increases the level of the water table.
