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

Which of the following is 'water wise habit'?

  1. Mop the floor instead of washing

  2. Keeping tap on while bath

  3. Washing your car daily

  4. Using excess water in kitchen
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Water wise habit is to conserve water by using alternatives to water or reducing the usage of water. Water is used for cleaning the floor, utensils etc 

Here instead of washing the floor it can be mopped
So, the correct answer is 'Mop the floor instead of washing'

Which one of the following is not a reason for shortage of usable water?

  1. Over exploitation

  2. Climate change

  3. Deforestation

  4. Decrease in sea level
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Water shortage is the water scarcity that may be caused by altered weather patterns including droughts or floods, increased pollution, and increased human demand and overuse of freshwater. Sea water cannot be used for daily activities because of the salt content. Thus, the correct answer is option D.

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.

Which of the following processes is involved in the water cycle?

  1. Evaporation, hibernation and dehydration

  2. Evaporation, condensation and precipitation

  3. Paddling, swimming and drinking

  4. Bathing, sunning and drinking
Reveal answer Fill a bubble to check yourself
B 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 earth as rain. Thus, the process like evaporation and condensation and precipitation plays an important role.

So, the correct answer is option B.

Rain fall patterns depend on 

  1. the underground water table

  2. The number of water bodies in an area

  3. The density of human population in an area

  4. The prevailing season in an area
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

More the number of water bodies in an area more is evaporation of water in that area. As a result, more clouds are formed and there is an increase in rainfall in that area.

So, option B" The number of water bodies in an area" is the correct answer. Rainfall pattern depends on water bodies in that area.

Which of the following process is not a step involved in water cycle operating in nature?

  1. Photosynthesis

  2. Evaporation

  3. Rain fall

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

  • The process of nitrogen metabolism is not involved in the water cycle. By the process of photosynthesis, plants absorb water from the soil. Through transpiration, they lose water back to the atmosphere through stomata.
  •  By the process of evaporation, water from water bodies is condensed leading to the formation of clouds. 
  • Clouds then shower rainfall that restores the water evaporated from water bodies and also the groundwater levels.

So, option D is the correct answer as all others are a part of the water cycle.

Which phase of water cycle gives us fresh water?

  1. Condensation

  2. Evaporation

  3. Precipitation

  4. Runoff
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The hydrological cycle is a prominent method to rejuvenate the fresh water resources. It involves the evaporation of water into water vapor by the heat of the sun which further condenses into tiny water droplets which fall on the earth as rain. The process of condensation that forms rain is also known as precipitation.

So, the correct answer is option C.

What is an aquifer?

  1. Underground lake

  2. Underground river

  3. Where water goes into ground

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

An aquifer is an underground body of permeable rock, rock fractures, or unconsolidated materials (gravel, sand, or silt) from which groundwater can be usefully extracted using a water well. Since none of the specific choices like underground lake or river correctly define an aquifer, none of the above is correct.

About how much water is recycled in the form of rains per year?

  1. 4.46 $\times 10^5$ gram per year
  2. 4.46 $\times 10^{10}$ gram per year
  3. 4.46 $\times 10^{20}$ gram per year
  4. 4.46 $\times 10^{30}$ gram per year
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Water exists at the earth's surface as liquid, solid, and vapour. It is changing from one of those three states to another. The total amount of water near the surface of the earth stays almost the same through time. One of the most important steps in the water cycle involves evaporation of water from the ocean surface, transport in the form of water vapour to the continents by winds, and precipitation as rain or snow on the continents. The rainfall then runs off by way of streams, rivers, and groundwater back to the ocean. Almost 4.46 10^20 gram per year of water is recycled in the form of rains per year.

Therefore, the correct answer is option C.
