12. Assertion (A) : Graben is a major relief feature resulting form the faulting activities. It is, in fact, a valley or narrow trough bounded by one more parallel faults.
    Reason (R) : Block of the earth's crust may be relatively raised or lowered between more or less parallel faults. The lower part known as graben is formed due to the subsidence of middle part between two normal faults.
    
    

1. 1. Both (A) and (R) are individually true and (R) is the correct explanation of (A)
      

   
   
   

   2. Both (A) and (R) are individually true but (R) is not a correct explanation of (A)
      

   
   
   

   3. (A) is true but (R) is false

13. Consider the following land form characteristics
    1. Stream divides are sharp and ridge like resulting in a minimum of inter stream uplands.
    2. Extensive areas are at of near the base level of erosion.
    3. There are a few consequent trunk streams but few large tributaries. Numerous short tributaries and gullies are extending themselves by head ward erosion and developing valley systems.
    Which one of the following is the orderly sequence of landform characteristics given above in an idealized Fluvial Cycle ?

1. 1. 1,3,2

   
   
   

   2. 2,3,1

   
   
   

   3. 3,1,2

   
   
   

   4. 2,1,3

15. Match List - I (Classification of valleys) with List - II (Characteristic of valley) and select the correct answer using the codes given below the Lists
    

    	List - I		List - II
    F.	Consequent valley	1.	Draining in a direction opposite to that of the original Consequent valleys
    G.	Subsequent valley	2.	Showing no apparent adjustment to structural control
    H.	Insequent valley	3.	Course shifted form the original consequent erosible rocks
    J.	Obsequent valley	4.	Course determined by the initial slope of the land
    		5.	Valleys draining in the direction opposite to rock dip
