Multiple choice depletion of water table water a precious resource biology

Water consumption in a city depends on

  1. Size of the city.

  2. Population of the city.

  3. Demand of water.

  4. All of the above.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Water consumption of a city depends on the size of the city which is directly related to the population of the city and demand of water in the city. When population increases consumption of water in daily needs, like drinking, bathing cooking also increases. Similerly construction work increase which consume excess amount of water.

Multiple choice depletion of water table water a precious resource biology

Which of the following are reasons for depletion of underground water of a particular place?

  1. Population explosion

  2. Extensive urbanization

  3. Building concrete structures

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Depletion of underground water mainly cause by multiple factors like over population which increase water demand day by day. People move from rural area to urban for better lifestyle due this number of building are constructing. Concrete is main material used in building construction which take lot of water.

So, the correct option is 'All of the above'.

Multiple choice depletion of water table water a precious resource biology

Identify the reason for water scarcity.

  1. Increasing rate of population

  2. Increasing rate of industries

  3. Both A and B

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

70% of the earth's surface is covered with water, yet only around 3%  is fit for human consumption.The remaining is frozen or salty.The consumption of water goes on increasing due to population,eventually leading to scarcity of water. The industrial wastes pollute the water reservoirs, making it unfit for human consumption.

Multiple choice depletion of water table water a precious resource biology

Which of the following is  the greatest user of ground water?

  1. Chemical purposes

  2. Rural water supply

  3. Agriculture

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The water present underground within cracks in between the rocks, soil or sand known as groundwater. This groundwater is replenished by the rain water that seeps into the soil through the cracks. It forms around twenty percent of the world's fresh water supply and is the major source of water in rural areas. Thus the correct answer is option B.

Multiple choice depletion of water table water a precious resource biology

The main cause of water depletion is

  1. Over-pumping groundwater

  2. Water Pollution

  3. Global warming

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The main cause of water depletion is due to over pumping of ground water

due to increase in population.
Hence,
option $A$ is correct answer.

Multiple choice depletion of water table water a precious resource biology

Explanation

The following can be the solution for water scarcity caused by agriculture are:
a) knowledge and resources for producing more and better crops with less water.
b) drip water irrigation.
c) more efficient water management systems adapted to climate variability.


Multiple choice depletion of water table water a precious resource biology

Drip irrigation was commercialized first in by Israeli agronomists in the year of

  1. 1970's.

  2. 1980's.

  3. 1990's.

  4. 2000's.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Drip irrigation technology was developed and commercialized by Israeli engineers (notably Simcha Blass and his company) in the 1960s-1970s. The 1970s saw widespread commercial adoption of this water-efficient irrigation method, making option A correct. Later decades saw improvements but the initial commercialization was earlier.

Multiple choice depletion of water table water a precious resource biology

Why is agriculture the cause of water scarcity?

  1. Because a large amount of crops require quality water in huge quantities.

  2. Because agriculture is the largest user of water.

  3. Both A and B.

  4. None of these.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Use of water in agriculture is the main cause of water scarcity because a large amount of appropriate quality and quantity of water is essential for the production of crops which makes agriculture is the largest user of water.

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

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.

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

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. 

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

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. 

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

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.

The water table fluctuates:

  1. by climatic variations

  2. by the amount of precipitation used by vegetation

  3. by withdrawing excessive amounts of water from wells

  4. all of them
Reveal answer Fill a bubble to check yourself
D 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 hence it fluctuates by changes in seasons, precipitation or by withdrawing a large amount of water.
