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

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

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

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.

The water table of a place :

  1. changes from time to time

  2. changes from palce to place

  3. goes down when rains are less

  4. all of these
Reveal answer Fill a bubble to check yourself
D Correct answer
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
Reveal answer Fill a bubble to check yourself
A Correct answer
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.

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
Reveal answer Fill a bubble to check yourself
A Correct answer
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.

Deplaction of the water table is due to which of the following resion?

  1. insufficient rain fall

  2. industrial activities

  3. excess of tube wells

  4. all of them
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All the given reasons as insufficient rainfall, industrial activities and excessive use of ground water are responsible for the depletion of water table.

The water table is:

  1. the upper level of an underground surface in which the soil or rocks are permanently saturated with water.

  2. the upper level of an underground surface in which the soil or rocks are unsaturated with water.

  3. the lower level of an underground surface in which the soil or rocks are permanently saturated with water.

  4. the lower level of an underground surface in which the soil or rocks are unsaturated with water.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The water table is also known as ground water table in which water seeps into the ground and move downward till it reaches the stage of saturation. The velocity at which water flows underground depends on the permeability of the rocks.
