Alternatives to large dams does not exist.

management of water uses and limitations of dams air, water and soil management of natural resources biology

  1. True

  2. False

  3. Nither

  4. Either

Show answer
Correct Option: B
Explanation:
Dams play an important role for hydroelectricity power plants because electricity is produced from the energy of water which rotates the turbines and electricity is generated. However, construction of large dams requires a large space and manpower too. Many alternatives are there for electricity generation other than the hydroelectric power plants on dams. Solar energy and wind energy are great alternatives for this. Moreover, construction of large dams is expensive and therefore not economic. Dams also cause climatic changes because the reservoirs in hydroelectric power plants emit greenhouse gases.
Hence, the statement given in the question is incorrect. 
So, the correct answer is 'False'.

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

management of water uses and limitations of dams air, water and soil management of natural resources biology

  1. True

  2. False

  3. Nither

  4. Either

Show answer
Correct Option: A
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'.
