(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true.
Ans: (a)
The Himalayas in the Eastern part of India are known as -Purvanchal or Eastern Himalayas. The Brahamputra river marks its Easternmost boundary beyond Dihang gorge, the Eastern Himalayan range turns South along the North-Eastern boundary of India.

Direction: In the questions given below, there are two  statements marked as Assertion (A) and Reason  (R). Read the statements and chose the correct  option:
Q2: Assertion (A): The Northern plains are an agriculturally very productive part of India.
Reason (R): The Northern plains have fertile soil cover, adequate water supply, favourable climate and terrain.
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true.
Ans: (a) 
The Northern plains are formed by three river systems i.e. Indus, the Ganga and the Brahamputra along with their tributaries. These rivers deposit alluvium in these plains and make the plains agriculturally very productive. Besides fertile soil cover, the plains also have adequate water supply, favourable climate and terrain.

Direction: In the questions given below, there are two  statements marked as Assertion (A) and Reason  (R). Read the statements and chose the correct  option:
Q5: Assertion (A): The rivers flowing from mountains to plains tend to lose their speed.
Reason (R): The slopes become gentler over plains.
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true.
Ans: (a) 
Usually mountains have steep slopes which increase the speed and velocity of rivers. [a] But when rivers enter into plains the slopes become gentler and reduce the speed and velocity of these rivers. Such is the case with the Northern plains, where slopes are gentler.

Direction: In the questions given below, there are two  statements marked as Assertion (A) and Reason  (R). Read the statements and chose the correct  option:
Q6: Assertion (A): The Peninsular plateau has broad and shallow valleys and gentle hills with rounded tops.
Reason (R): The Peninsular Plateau is a part of the oldest landmass.
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true.
Ans: (a) 
The Peninsular plateau was formed due to the breaking up and drifting of Gondwana land. Thus it is a part of the oldest landmass. Due to the action of erosion and weathering, the plateau has broad and shallow valleys and gentle hills with rounded tops.

Direction: In the questions given below, there are two  statements marked as Assertion (A) and Reason  (R). Read the statements and chose the correct  option:
Q7: Assertion (A): The Eastern Ghats are discontinuous and irregular.
Reason (R): These Ghats are dissected by rivers flowing into the Bay and Bengal.
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true.
Ans: (a) 
The Eastern Ghats are not a continuous chain of mountains. They are broken because most of the peninsular rivers are east flowing rivers which are wide when flowing through these ghats and form deltas near the sea and drain into the Bay of Bengal.
