- Question 1 of 9
Question No. 1
1 pointsSandalwood is an example of:
CorrectCorrect Answer – Deciduous forest
The Moist deciduous forests are more pronounced in the regions which record rainfall between 100-200 cm. These forests are found in the northeastern states along the foothills of the Himalayas, eastern slopes of the Western Ghats and Odisha. Teak, sal, shisham, hurra, mahua, amla, semul, Kusum, and sandalwood etc. are the main species of these forests.Dry deciduous forest covers vast areas of the country, where rainfall ranges between 70 -100 cm. On the wetter margins, it has a transition to the moist deciduous, while on the drier margins to thorn forests. These forests are found in rainier areas of the Peninsula and the plains of Uttar Pradesh and Bihar.
In the higher rainfall regions of the Peninsular plateau and the northern Indian plain, these forests have a parkland landscape with open stretches in which teak and other trees interspersed with patches of grass are common. As the dry season begins, the trees shed their leaves completely, and the forest appears like a vast grassland with naked trees all around. Tendu, palas, amaltas, bel, khair, axlewood, etc. are the common trees of these forests. In the western and southern part of Rajasthan, vegetation cover is very scanty due to low rainfall and overgrazing.

1 pointsWhich one of the following was the purpose of Project Tiger?
CorrectCorrect Answer – to protect tigers from illegal hunting
Special schemes like Project Tiger (1973) and Project Elephant (1992) have been launched to conserve these species and their habitat in a sustainable manner. Project Tiger has been implemented since 1973. The main objective of the scheme is to ensure maintenance of the viable population of tigers in India for scientific, aesthetic, cultural and ecological values, and to preserve areas of biological importance as a natural heritage for the benefit, education and enjoyment of the people. Initially, the Project Tiger was launched in nine tiger reserves, covering an area of 16,339 sq. Km, which has now increased to 44 tiger reserves, encompassing 36,988.28 sq. Km of core tiger habitats distributed in 17 states. The tiger population in the country has registered an increase from 1,411 in 2006 to 1,706 in 2010.

Question No. 5
1 pointsWhich one of the following proportion of the area of the country was targeted to be under forest in Forest Policy of India?
CorrectCorrect Answer – 33
Forests have an intricate interrelationship with life and environment. These provide numerous direct and indirect advantages to our economy and society. Hence, conservation of forest is of vital importance to the survival and prosperity of humankind. Accordingly, the Government of India proposed to have a nation-wide forest conservation policy and adopted a forest policy in 1952, which was further modified in 1988. According to the new forest policy, the Government will emphasise sustainable forest management to conserve and expand forest reserve on the one hand, and to meet the needs of local people on the other.
The forest policy aimed at (i) bringing 33 percent of the geographical areas under forest cover; (ii) maintaining environmental stability and to restore forests where ecological balance was disturbed; (iii) conserving the natural heritage of the country, its biological diversity and genetic pool; (iv) checks soil erosion, extension of the desert lands and reduction of floods and droughts; (v) increasing the forest cover through social forestry and afforestation on degraded land; (vi ) increasing the productivity of forests to make timber, fuel, fodder and food available to rural population dependant on forests, and encourage the substitution of wood; (vii) creating of a massive peoples movement involving women to encourage planting of trees, stop felling of trees and thus, reduce pressure on the existing forest.

- Question 6 of 9
Question No. 6
1 pointsWhat causes rainfall on the coastal areas of Tamil Nadu at the beginning of winters?
CorrectCorrect Answer – North-Eastern monsoon
During October and November, northeast monsoon while crossing over the Bay of Bengal, picks up moisture and causes torrential rainfall over the Tamil Nadu coast, southern Andhra Pradesh, southeast Karnataka and southeast Kerala.
Here it is important to know why the Tamil Nadu coast remains dry during this season. There are two factors responsible for it: (i) The Tamil Nadu coast is situated parallel to the Bay of Bengal branch of southwest monsoon. (ii) It lies in the rainshadow area of the Arabian Sea.
