Multiple choice chemistry water too little to waste pollution of water water pollution planet earth

Which of the following activity causes water depletion?

  1. Increasing population

  2. Increasing industries

  3. Agricultural activities

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

Factors responsible for the depletion of water table-

(i) Population- due to the increase in population, the open area decreases in order to fulfill the demands such as the house, shops, roads, pavements, office, etc, thereby cutting trees resulting in deforestation which decreases the open area for the seepage of water into the ground.
(ii) Agriculture- for agricultural process water is needed for irrigation for which ground water is used which in turn decreases the water table.
(iii) Most of the people keep the taps open though water is not in use, this is how wastage of water resources occur.
Many industrial practices cause water pollution, for eg-mining, drilling. Oil spills also cause water pollution. These type of pollution leads to depletion of water.

Multiple choice geography manufacturing industries in india - i : agro-based location of industries distribution and classification of industries in india industrialisation and industrial belts

Heavy water plants are generally located near ______.

  1. Major irrigation projects

  2. Hydroelectric projects

  3. Fertilizer plants

  4. Nuclear power plants
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Heavy water plants are generally located near fertilizer plants. Heavy water  is used in the production  of fertilisers , so it is often seen that heavy water plants are  near  to the fertilisers industry. As the plants  are near, the cost of transportation gets reduced and use of heavy water  can be proper without any wastage.

Multiple choice evs sources of water the lithosphere and the hydrosphere first aid safety and first aid

Rain is the ultimate source of water.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • The ultimate source of water is the water bodies which are present on earth which includes large oceans, seas, rivers, etc. Rain is only the way of water returning to their sources which they have lost by evaporation.
  • This rain is not an ultimate source of water .the ultimate source are the water bodies present on earth example large oceans, rivers etc
  • So, the correct answer is 'False'.

Which one of the following is not responsible for water shortage ?

  1. Rapid growth of industries.

  2. Increasing population

  3. Heavy rainfall

  4. Mismanagement of water resources
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Water is one of the most valuable resources on Earth. Rainwater fills reservoirs that supply drinking water, provide a habitat for fish to live, and nourishes the soil with water necessary for vegetation.
  • Hence Heavy rainfall is not responsible for water shortage.
  • So, the correct answer is 'Heavy rainfall'.

Primary source of water is

  1. Rivers

  2. Ground water

  3. Lakes

  4. Rainwater
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The primary source of water on the surface of the earth is rain. Rain is mainly formed due to the precipitation of vapours accumulated due to evaporation. Some part of the rainwater is available as ground water which can be used in case of adversity.

So, the correct answer is option D.

Which of the following plays a very important role in causing rainfall?

  1. Factories

  2. Vehicles

  3. Plants

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

Transpiration is the process in which plants lose water as water vapor during photosynthesis. This water is added to the moisture in air saturating it and hence generating rainfall. Thus the correct answer is option C.

The fresh water is continually being renewed and recharged through

  1. Hydrological cycle

  2. Carbon cycle

  3. Nitrogen cycle

  4. Life cycle
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The hydrological cycle is a prominent method to rejuvenate the fresh water resources. It involves the evaporation of water into water vapour by the heat of the sun which further condenses into tiny water droplets which fall on the earth as rain. This continuous recycling of water leads to recharging of the water resources.

Which of the following play a very important role in causing rainfall ?

  1. Animals

  2. Plants

  3. Factories

  4. Vehicles
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Transpiration in plants plays a vital role in the water cycle. The plants transpire and lose water in the form of gases from its aerial parts which increases the moisture content in the atmospheric air. So, the air gets saturated with moisture at a faster rate and causes rainfall. Thus, the correct answer is option B.
