1. The paleomagnetic results obtained from India indicate that in the past , the Indian land mass has moved : [U.P.P.C.S.(Pre) (1998 ) I.A.S(Pre) (1995)]

(a) Northward
(b) Southward
(c) Eastward
(d) Westward

Correct Answer: (a) Northward

Solution:The Indian Landmass has moved northward. This is evident from the paleomagnetic results obtained from India . Even the extension of the plateau region in the north side is evident . Paleomagnetism is the study of the record of the earth magnetic field in rock , sediment or archeolpgical material . This record provides information on the past behaviour of earth magnetic field and the past location of tectonics plates . According to continental drift theory Indian land mass was Antarctica , Australia , Africa and Peninsular India . This large land mass broke and Indian land mass moved north wards . Vindhya and western ghat mountains emerged during this period .

2. The Indian subcontinent was originally part of a huge mass called : [I.A.S(Pre)(1995)]

(a) Jurassic land mass
(b) Aryavarta
(c) Indiana
(d) Gondwana Continent

Correct Answer: (d) Gondwana Continent

Solution:The Indian subcontinent was originally part of a huge landmass called Gondwana Continent . Gondwana was an ancient supercontinent that broke up about 200 million years ago . The continent eventually split into landmass that we recognize today as Africa , South America , Australia , Antarctica , the Indian subcontinent and the Arabian Peninsula.

3. Indian is divided into how many Natural Territories ? [R.A.S./R.T,S (Pre)(1996)]

(a) 4
(b) 6
(c) 7
(d) 8

Correct Answer: (a) 4

Solution:India is Divided into four main natural regions . These are -
1. Northern mountains region
2. Large Plains
3. Peninsular Plateau
4. Coasts and Islands
It is further categorized in six sub -physical region :
1. Northern Mountains
2. Sindhu-Ganga Plains
3. Thar desert
4. Central highland and deccan plateau
5.Coastal Plains
6. Sea and islands

4. In which part of Uttarakhand are artesian wells found ? [Uttarakhand P.C.S.(Mains)(2006)]

(a) Bhabhar
(b) Tarai
(c) Shivalik hills
(d) None of the above

Correct Answer: (b) Tarai

Solution:An artesian well is simply a well that doesn't require a pump to bring water to the surface . This occurs when there is enough pressure is the aquifer . The pressure forces the water to the surface without any sort of assistance . In Uttarakhand artesian wells are mostly found in the Tarai region .

5. Consider the following statements regarding formation of landforms in Indian : [47th B.P.S.C.(Pre)(2005)]

1. Structurally, the Meghalaya plateau is an extended part of the Deccan plateau .
2. The Valley of Kashmir was formed in a synclinorium.
3. The Gangetic plain was formed in a fore deep .
4. The Himalayas originated as a results of triangular convergence of the Indian plate , the European plate and the Chineses plate.
Which of these statements are correct ?

(a) 1 , 2 and 3
(b) 1 ,3 and 4
(c) 1,and 3
(d) 2, and 4

Correct Answer: (a) 1 , 2 and 3

Solution:Meghalaya plateau is an extension of the Peninsular plateau . It is believed that due to the force exerted by the north eastward movement of the Indian plate at the time of the Himalayan origin , a huge fault was crested between the Rajmahal hills and the Meghalaya plateau . Later,this depression got filled up by the deposition activity of numerous rivers. Today the Meghalaya and Karbi Anglong plateau stand detached from the main Peninsular Block. Thus statement (1) is correct . The Valley of Kashmir was formed in a synclinorium . The Indo-Gangetic basin is an active foreland basin having east -west elongated shape . The basin formed is response to the uplift of Himalaya after the collision of India and China plates ( Dewey and bird , 1970 ). Suess ( 1893-1909) was the first geologist to suggest that the Indo- Gangetic depression is A 'fore deep ' and was formed in front of the high crust - waves of the Himalayas as their southward migration was resisted by the Himalayas as their southward migration was resisted by the rigid Landmass of the Peninsula.
Thus statements (3) is also correct . The Himalayas mountain range and Tibetan plateau have formed as a result of the collision between The Indian plate and the Eurasian plate . Chinese plate is not mentioned in the theory of plate tectonics . Thus statements (4) is wrong .

6. Which of the Following statements is incorrect ? [U.P. Lower Sub. (Pre)(2004)]

(a) Geologically peninsula region is India' most ancient part .
(b) Himalaya mountains demonstrate the most newly developed folded mountains in the world .
(c) The western coastline of India is formed by the deposition of the rivers .
(d) Gondwana rocks have the largest reserve of coal in India .

Correct Answer: (c) The western coastline of India is formed by the deposition of the rivers .

Solution:The Western coastline of Indian is not formed by the deposition process of the rivers In the fact , it is formed by submergence and emergence of the land . Gondwana rocks have the largest reserve of cool in India. Himalaya is the newly developed folded mountains . Geologically , Peninsular region is the most ancient part of India . Thus statement (c) is incorrect .

7. Match List 1 with list 2 and select the correct answer : [I.A.S.(Pre)(1997)]

List - 1	List - 2
A. Deccan Traps	1. Late Cenozoic
B. Western Ghats	2. Pre-Cambrian

Code :

	A	B	C	D
a	3	5	1	4
b	3	1	2	5
c	2	1	3	4
d	1	4	2	5

Correct Answer: (b)

Solution:The correctly matched order is :
The origin of the Deccan Traps - Cretaceous Eocene

Narmada-Tapi alluvial deposits -Pleistocene period

8. Kuttanad (or Kuttanadu) of Kerala is famous for : [U.P.P.C.S.(Mains)(2015)]

(a) A freshwater lake
(b) The region with the lowest altitude in india

Correct Answer: (b) The region with the lowest altitude in india

Solution:Kuttanad ( or Kuttanadu ) of Kerala is famous for its lowest altitude in India . Kuttanad is called the Rice Bowl of Kerala .

10. Which one of the following districts does not have Dharwar geological formations? [65th B.P.S.C.(Pre)(2019)]

(a) Munger
(b) Rohtas
(c) Jamui
(d) Nawada

Correct Answer: (b) Rohtas

Solution:Rohtas District does not have Dharwar grological formations . Districts havings Dharwar land level composition in Bihar come under South -East Bihar . These are Munger, Nawada and Jamui districts . Whereas Rohtas is a part of South -East Bihar. Vindhyan type of ground level formatiom is found in this area . In Bihar , Vindhyan ground level formation is found in Kaimur and Son river valley (Rohtas).
