Environment & Biodiversity MCQs

Notes:
The local name of sacred groves of Tamil Nadu are known with the names of Swami shola and Koilkadu. They are total 752 in number. Orans, Kenkris, Jogmaya are the sacred groves of  Rajasthan.

Notes:
The term smog was first used by Dr. H.A. Des Voeux in 1905. Smog is a condition of fog that also contains soot or smoke in it. It is a type of intense air pollution that reduces visibility.

Notes:
Combustion of solid material leads to the production of Ash. Fly ash is a very fine powder which tends to travel far in the air. The ash which does not rise in the air is termed as bottom ash.

Notes:
The Government of India enacted the Energy Conservation Act in the year 2001. The Energy Conservation Act is an act to provide for the efficient use of energy and its conservation.

Notes:
The branches of sustainability include the environment, the needs of present and future generations and the economy. Sustainable development is the type of development that meets the needs of the present generations without compromising the ability of future generations to meet their own needs.

Notes:
Lingambudhi Lake is situated in Mysuru city, Karnataka. Mysuru is known for its lakes and parks, and Lingambudhi Lake is a well-known water body in this region. It serves as an important ecological and recreational area within the city limits.

Notes:
Gases that trap heat in the atmosphere are called green house gases. Global Warming Potentials (GWPs) are used to compare the abilities of different green house gases to trap heat in the atmosphere. Carbon dioxide is used as the base for all the calculations, so its global warming potential is 1.2. The higher the GWP, the more heat the specific gas can keep in the atmosphere. Fluorinated gases : Chlorofluorocarbons, Hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen trifluoride : are synthetic, powerful greenhouse gases that have highest heat trapping abilities. These gases are 1,000; 10,000 even 20,000 times more powerful than Carbon dioxide (CO2) at trapping heat and many can stay in our atmosphere for thousands of years.

Notes:
Checking atomic blasts will reduce radioactive pollution. Sewage pollution can be prevented by treating sewage before passing into water course, in sewage treatment plant or effluent treatment plant (ETP). Electrically operated vehicles will control automobile exhaust and improve the air quality in cities. Environmental pollution can be controlled by treating factory wastes before disposing of them. So, if we treat wastewater before disposing of in a river, it will surely decrease the amount of dumped pollutants. For example- Steel industries have a high concentration of cyanide in it, and it led to harmful effect. So, treatment is really necessary.

Notes:
The Keibul Lamjao National Park is a national park in the Bishnupur district of the state of Manipur in India. It is 40 km2 (15.4 sq mi) in area, the only floating park in the world, located in North East India, and an integral part of Loktak Lake. It was created in 1966 as a wildlife sanctuary to preserve the natural habitat of the endangered Eld’s deer. In 1977, it was gazetted as national park.

Notes:

• The Asian Waterbird Census is conducted in January each year and is coordinated by the Wetlands International South Asia and the Bombay Natural History Society in india.
• It is an integral part of the global waterbird monitoring programme, the International Waterbird Census (IWC), coordinated by Wetlands International.
• It was initiated in 1987 in the Indian subcontinent and since has grown rapidly to cover major region of Asia.
• It is the longest-running citizen science initiative.
• Under this initiative, systematic counting and monitoring of waterbirds is undertaken to study trends and condition of wetlands, covering hundreds of sites.
