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.

What is the origin of energy that drives the water cycle?

  1. Trees

  2. Water

  3. Mountains

  4. Sun
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • The hydrological cycle is a prominent method to rejuvenate the freshwater resources. 
  • It involves the evaporation of water into water vapor by the heat of the sun which further condenses into tiny water droplets that fall on the earth as rain.
  • This continuous recycling of water leads to the recharging of water resources. 
  • The solar radiation plays an important role in the water cycle.

    Hence, option D is correct.

Water cycle is made up of which of the two overlapping cycles?

  1. Surface waters and atmospheric cycles

  2. Oceanic and fresh water cycles

  3. Ground water and atmospheric cycles

  4. Global and smaller cycles
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

  • The global water cycle describes the water movement globally. It is a complex pathway that includes the passage of water from the gaseous envelope around the planet called the atmosphere, through the bodies of water on the surface of the earth such as the oceans, glaciers, and lakes, and at the same time passing through the soil and rock layers underground. 
  • Later, the water is returned to the atmosphere. A fundamental characteristic of the hydrologic cycle is that it has no beginning and it has no end. It can be studied by starting at any of the following processes: evaporation, condensation, precipitation, interception, infiltration, percolation, transpiration, runoff, and storage. 

Therefore, the correct answer is option D.

Which of the following functions performed by a forest help most in controlling drought?

  1. Forests prevent soil erosion

  2. Forests bring rainfall

  3. Forest have lot of water plants

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Forests help mitigate drought by increasing local humidity and rainfall through transpiration, and by preventing soil erosion, which maintains the soil's water-holding capacity. Since both statements A and B are correct, D is the best choice.

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.

Water cycle leads to change in

  1. Pressure

  2. Humidity

  3. Temperature

  4. Both B and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

During evaporation, water takes up energy from its surroundings and cools the environment. It releases energy when it condenses and warms the environment. This causes a change in the temperature as well as the humidity of the surrounding. Thus the correct answer is option D.

Transfer of heat within water is by

  1. Conduction

  2. Convection

  3. Radiation

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

The water is a poor conductors of heat so do not heated by conduction.  When water is heated, the water became lighter. Hot water rises up. The cold water from the sides moves  down towards the source of heat. This water also gets hot and rises and water from the sides moves down.  This process continues till the whole water gets heated. This mode of heat transfer is known as convection.

So, the correct answer is 'Convection'.

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.
