Questions Related to groundwater and depletion of water table

Rainfall patterns depend on

evs sources of water and water cycle groundwater and depletion of water table rain: where does it come from availability and forms of water the water cycle

  1. The underground water table

  2. The number of water bodies in an area

  3. The density pattern of human population in an area

  4. The prevailing season in an area.

Show answer
Correct Option: B
Explanation:

Rainfall pattern will depend on number of water bodies in an area, as there will be large water bodies, (ocean, river) the rate of evaporation would be high, which will help to cause rain in the area.

More than 70% of world's fresh water is contained in

evs sources of water and water cycle groundwater and depletion of water table rain: where does it come from availability and forms of water the water cycle

  1. Antarctica

  2. Polar ice

  3. Glaciers and Mountains

  4. Greenland

Show answer
Correct Option: B
Explanation:
More than 70% of world's fresh water is contained in Polar ice. These polar ice are present in the form of two sheets in Antartica and Greenland.
So, the correct answer is 'Polar ice'.

  2. More quickly, more slowly

  3. More slowly, more quickly

  4. More slowly, more slowly

Show answer
Correct Option: D

  2. Pollutions

  3. Air pollution

  4. Water Pollutions

Show answer
Correct Option: A

  1. 1.3 mm/yr

  2. 1.8?mm/yr

  3. 1.7 mm/yr

  4. 1.9 mm/yr

Show answer
Correct Option: B

The water table of a place :

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

  1. changes from time to time

  2. changes from palce to place

  3. goes down when rains are less

  4. all of these

Show answer
Correct Option: D
Explanation:

Water table is also called ground water table and it changes from time to time, and from place to place according to availability of sources and it goes down when rains in monsoon season are less.

In a small town, the number of water pumps, concrete houses and roads increased. The water table of that place will :

  1. get lower

  2. get higher

  3. remain unaffected

  4. none of these

Show answer
Correct Option: A
Explanation:

The level of water table falls in a place, where the number of water pumps increases because with the help of water pumps groundwater is extracted and this depleted groundwater is not replaced as concrete houses and roads do not allow the rainwater to seep through the soil.

Water found in wells :
social science water: a precious resource water table groundwater and depletion of water table the water cycle

  1. contain sodium carbonate

  2. is underground water

  3. contain distilled water

  4. contain ice

Show answer
Correct Option: B
Explanation:

Water found inn wells is underground water ground water is a found in underground aquiters where it is naturally feltued through many layers of rock and sand.

In a small town, the number of water pumps, concrete houses and roads increased. The water table of that place will:

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

  1. get lower

  2. get higher

  3. remain unaffected

  4. none of these

Show answer
Correct Option: A
Explanation:

Due to number of water pumps the water level decreases due excess use of water, and if the number of roads and houses increases the rainwater absorption decreases so that ground water cannot refill after the excess use. 

The minimum depth in the soil where all the spaces are filled with water is called:

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

  1. saturation level

  2. ground water table

  3. ground water

  4. water table

Show answer
Correct Option: D
Explanation:

The minimum depth in the soil where all the spaces are filled with water is called the water table.

So, option (D) is the correct answer.
