Check dams are build along seasonal flooded gullies for water harvesting.

  1. True

  2. False

  3. Nither

  4. Either
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
A check dam is a small dam which may be temporarily or permanently constructed across a gully, a draining ditch or channel so as to slow down the speed of concentrated flows. These dams are made for harvesting water and preserving natural water of rain. Hence, these dams are made in seasonal times generally when there is heavy rainfall. The stored water then can be used for various purposes.
Hence, the statement given in the question is correct.
So, the correct answer is 'True'.

The collection of rainwater in the storage tank for reuse can be termed as

  1. Water harvesting

  2. Potable water

  3. Water pollution

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

Rainwater harvesting reuse of water. The term 'rainwater harvesting' refers to the collection of precipitation running off roof surfaces into cisterns or other storage vessels. Storm water reuse refers to the collection of runoff from catchment surfaces (e.g. roads, parking lots and landscaped areas).

So, the correct answer is 'Water harvesting'

Which of the following is the benefit of water harvesting?

  1. It could be utilized for irrigation purposes.

  2. This water increases the underwater level.

  3. It could be utilized for domestic purposes.

  4. All of the above

D Correct answer
Explanation

Water harvesting systems provide versatile benefits, including recharging groundwater, providing water for irrigation, and supplying domestic needs.

All of the following are advantages of dams except

  1. flood control

  2. recreation

  3. hydroelectric power

  4. enhancing natural spawning patterns of fish
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

While dams offer benefits like flood control and power generation, they often disrupt aquatic ecosystems and block the natural migration and spawning patterns of fish.

It is important to make small check dams across the flooded gullies because they
(i) Hold water for irrigation
(ii) Hold water and prevent soil erosion
(iii) Recharge ground water
(iv) Hold water permanently

  1. (i) and (iv)

  2. (ii) and (iii)

  3. (iii) and (iv)

  4. (ii) and (iv)

  5. (i), (ii) and (iii)
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

A major portion of water stored behind dams in the world is withdrawn for irrigation that is, evaporation and transpiration needs. Water used in excess of evaporation and transpiration needs appears in the system as surface or groundwater. The total quantum of flow and size and frequency of peak floods in the flood season reduce in the downstream due to a dam, reducing flood hazard due to inundation of land, crop and property. It also reduces congestion of run off in plains and coastal lands. Any soil erosion such as gullies already formed can be tackled by the construction of dams or obstructions. 

Therefore, the correct answer is option E.

The drawback of dam is

  1. Block fish migration

  2. Can cause flood on dam side area

  3. Displace local people

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

Large dams are frequently criticized for their negative social and environmental impacts, including blocking fish migration, increasing flood risks in certain areas, and displacing local communities.

Making of small check dams across the flooded gullies is important because they

  1. hold water and prevent soil erosion

  2. recharge ground water

  3. help stagnate water

  4. hold water for irrigational purpose
Reveal answer Fill a bubble to check yourself
A,C Correct answer
Explanation

Check dams are small barriers built across gullies to slow down water flow, which helps in retaining water, reducing soil erosion, and facilitating groundwater recharge.

Multiple choice zoology excretion in living organisms excretion - animals human excretory system and products excretory system and products excretion - plants excretion in plants

Animals return water to the environment by
(i) Perspiring
(ii) Drinking
(iii) Urinating
(iv) Breathing

  1. (i), (iii) and (iv)

  2. (i) and (ii)

  3. (i) and (iii)

  4. (iii) and (iv)
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A) Perspiration (sweating) is the loss of water and salts through the surface of the skin. This water evaporates. Urine is mostly water and is also composed of salts and is excreted by the animal into the environment. While breathing, minute molecules of water or water vapour are given out into the environment along with carbon dioxide.

B) While drinking water, the animal consumes it from the environment.
C) Perspiration and urination release water into the environment.
D) Breathing releases water in form of water vapour into the environment.
So, the correct answer is '(i), (iii) and (iv)'.
