  1. 11%

  2. 22%

  3. 30%

  4. 60%

Show answer
Correct Option: D
Explanation:

In India 6, 77,088 square kilometer of land is under forest cover. The figure was 30 percent at the beginning of 20th century.  

As per World Bank estimates the forest cover in India was 22 percent in the year 2000 and 23 percent in 2010. 
The present forest cover is quite small as compared to optimum of 33 percent according to National Forest Policy, 1988.
Since the 1952 NFP (National Forest Policy in India), there has been an advocacy for 33% forest cover with a 60% forest cover in mountainous and hilly regions.

According to forestory comission report - 1997 the total forest cover of India

  2. 33%, 67%

  3. 20%, 33%

  4. 70%, 30%

Show answer
Correct Option: B
Explanation:

India launched its 'National Forest Policy' in 1988. This led to a programme named 'Joint Forest Management', which proposed that specific villages in association with the forest department will manage specific forest blocks. In particular, the protection of the forests would be the responsibility of the people. The percentage of forest cover in India, for plain and hills as decided by 'Forest Policy Act' (1988) is 33% and 67% respectively.

Precipitation and groundwater are sources of _________.

evs - i hydrologic cycle the atmosphere elements of weather and climate :humidity hydrologic cycle and its components elements of weather and climate : temperature

  1. Fresh water

  2. Pure water

  3. Rain water

  4. Sea water

Show answer
Correct Option: A
Explanation:

  • Globally water occupies a major portion. Water constitutes 96.5 % on the earth and rest is land. Of the total water content fresh water contributes a very little portion of 2.5%. Fresh water sources include:
  • Groundwater - water found in shallow aquifers beneath the earth's surface. This water is generally found at depths up to around 2,000 feet deep.
  • Precipitation: It is nothing but the rain water which is an important source of fresh water. In fact it is the purest natural source of fresh water.

The process by which water continually changes its form and circulates between oceans, atmosphere and land _____________.

evs - i hydrologic cycle the atmosphere elements of weather and climate :humidity hydrologic cycle and its components elements of weather and climate : temperature

  1. Tides

  2. Water cycle

  3. Rain

  4. Ocean currents

Show answer
Correct Option: B
Explanation:

The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation.

  2. (i) - Meghalaya and Maharashtra; (ii) - Rajasthan; (iii) - Madhya Pradesh

  3. (i) - Madhya Pradesh; (ii) - Rajasthan; (iii) - Meghalaya

  4. (i) - Rajasthan; (ii) - Meghalaya; (iii) - Karanataka and Maharashtra

Show answer
Correct Option: A
Explanation:

(i) In Meghalaya sacred groves represent a long tradition of environmental conservation based on indigenous knowledge by the tribal communities. They are among the few least disturbed forest patches which are serving as the natural treasure house of biodiversity and a refuge for a large number of endemic, endangered and rare taxa. The general term for sacred groves in the Khasi Hills is 'Khlaw Kyntang' or 'Law Kyntang' or 'Law Lyngdoh' while in the Jaintia Hills it is called 'Khloo Blai'. The sacred groves in the Khasi Hills and Jaintia Hills District are fundamentally based on the traditional religious belief of the tribals i.e., Khasis and Pnars, which is called Seng Khasi and Niam Tre respectively.

(ii) Sacred Groves are found from the western part of Rajasthan to the east of the Aravalli range. These groves are known under various names in Rajasthan as sacred groves (deora, malvan, deorai, rakhat bani, oran, etc.), sacred corridors (deo ghats), temple forests (mandir van) and sacred gardens (baugh). Brandis, as early as 1887, gave initial information on sacred groves of Aravallis. He wrote, 'though very few papers have been published on sacred groves, this does not mean that such areas do not abound in India'. 
(iii) Western Ghats also known as Sahyadri (Benevolent Mountains) is a mountain range that runs parallel to the western coast of the Indian peninsula. Forest clearance was inevitable for farming and yet, there was an overwhelming belief in the sacredness of the woods.  They were important tracts of pre-colonial forest conservation in the Western Ghats. Myriad relics of such groves, exist even today all over the Western Ghats. They may be called Devrai in Maharashtra, Devarkadu in Kodagu and Kavu in Kerala and Tamil Nadu, these forests in pre-colonial landscape, served many functions like the conservation of biodiversity and watershed, moderation of climate and promoted varied wildlife.
So the correct option is ' (i) Meghalaya, (ii) Rajasthan (iii) Karnataka and Maharashtra'.
