  4. Unit of life

Show answer
Correct Option: C
Explanation:

Water is essential for all living beings (human, animal and plant) for various
metabolic reactions. They gain water not on;y through the action of drinking but also from the food they eat.

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 :

  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:

  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.

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

Show answer
Correct Option: D
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:

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

  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.

Show answer
Correct Option: A
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.
