Multiple choice 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

The freshwater stored in the ground is much more than that present in the rivers and lakes of the world.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Groundwater is the water found underground in the cracks and spaces in soil, sand, and rock. It is stored in and moves slowly through geologic formations of soil, sand, and rocks called aquifers.
  • Groundwater is the source of about 33 % of the water that county and city water departments supply to households and businesses (public supply).
  • Hence The freshwater stored in the ground is much more than that present in the rivers and lakes of the world is a true statement.
  • So, the correct answer is 'True'.

In water cycle, the maximum vaporization takes place:

  1. from oceans

  2. from rivers

  3. from streams

  4. from plants
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

86% of global evaporation occurs from the ocean due to its large surface area which directly comes in contact with sun rays and gives maximum vaporisation.


Hence, option A is correct.

Which of the following is not naturally occurring form of water?

  1. Solid

  2. Liquid

  3. Vapour

  4. Semi-solid
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Water exists in liquid form upto  $100^0$C , at 100$^0$C it exists as vapour and at 4$^0$C it exists in solid form  as ice. So water exists in all the states or forms except semisolid, jelly state

So, the correct answer is 'Semi-solid'

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
Reveal answer Fill a bubble to check yourself
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.

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
Reveal answer Fill a bubble to check yourself
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.
