Answer: A

Explanation:

The rivers coming from the northern mountains are engaged in depositional work. Due to low slope in the lower parts of the river, the speed of the river decreases. As a result, river islands are formed. These rivers get divided into many streams due to accumulation of silt in their lower part. These streams are called distributaries. Hence, statement 1 is correct while statements 2, 3 and 4 are incorrect.

Answer: C

Explanation:

The northern plain of India is broadly divided into three sub-categories. The western part of the northern plain is called the Punjab Plain. A large part of this plain formed by the Indus and its tributaries lies in Pakistan. The Indus and its tributaries Jhelum, Chenab, Ravi, Beas and Sutlej originate from the Himalayas. The western part of the plain has a large number of doabs. Hence, statements 1 and 2 both are correct.

Answer: C

Explanation:

The northern plains are generally described as a plain with no variation in its relief features. These vast plains also have varied topography. Hence, statement 1 is correct.

The rivers while descending from the mountains deposit silt in a strip of 8 to 16 km wide on the slopes of the Shivalik. This is known as 'Bhabar'. All the streams vanish in this Bhabar belt. Hence, statement 2 is correct.

The largest part of the northern plain is made up of old alluvium. They are situated above the flood plains of the rivers and show a terrace-like shape. This part is known as 'Bhangar'. Calcareous deposits are found in the soil of this area which is called 'Kankad' in the local language. Hence statement 3 is correct.

Answer: A

Explanation:

The largest part of the northern plain is made up of old alluvium. They lie above the flood plains of rivers and show a terrace-like shape. This part is known as 'Bhangar'. The soil of this region contains calcareous deposits, which are called 'kankar' in the local language. The new and young deposits of the flood plains are called 'Khadar'. They are re-formed almost every year. Hence, they are fertile and ideal for intensive cultivation. Hence, option (a) is correct.

Answer: C

Explanation:

The Peninsular Plateau is a table-shaped landmass made up of old crystalline, igneous and metamorphic rocks. Hence, statement 1 is correct.

It was formed due to the break-up and erosion of the Gondwana land and hence, it is a part of the oldest landmass. Hence, statement 2 is correct.

This plateau region has wide and shallow valleys and rounded hills. This plateau has two main parts - 'Central Highlands' and 'Deccan Plateau'. Hence, statement 3 is correct.
