QUESTION: 1

The Terai region is a

Solution:
  • It was in the news due to Nepalese constitution issues.

  • The Northern plains can be divided into four regions - two are discussed here.

  • After descending from the mountains, the rivers deposit pebbles in a narrow belt of about 8 to 16km in width lying parallel to the slopes of the Shivalik. It is known as bhabar.

  • All the streams disappear in this bhabar belt. South of this belt, the streams and rivers re-emerge and create a wet, swampy and marshy region known as terai. This was a thickly forested region full of wildlife. The forests have been cleared to create agricultural land and to settle migrants from Pakistan after partition.

QUESTION: 2

Consider the following statements on Northern Plains of India:

1. It was a geo-synclinal depression.

2. It has been gradually filled by the sediments brought by Himalayan and Peninsular rivers.

3. Average depth of alluvial deposits in these plains ranges from 1 to 2 km.

Which of the statements given above is/are correct?

Solution:
  • India's third geological division comprises the plains formed by the river Indus, the Ganga and the Brahmaputra Originally.

  • It was a geo-synclinal depression that attained its maximum development during the third phase of the Himalayan mountain formation approximately 64 million years ago.

  • Since then, it has been gradually filled by the sediments brought by the Himalayan and Peninsular rivers Average depth of alluvial deposits in these plains ranges from 1,000 to 2,000 m.

Geosyncline

  • It is a linear trough of subsidence of the Earth's crust within which vast sediment accumulate.

  • The filling of a geosyncline with thousands or tens of thousands of feet of sediment is accompanied in the late stages of deposition by folding, crumpling, and faulting of the deposits, the intrusion of crystalline igneous rock and regional uplift along the axis of the trough generally complete the history of a particular geosyncline, which is thus transformed to a belt of folded mountains,

QUESTION: 3

Consider the following statements concerning regions of Northern plains of India:

1. The rivers, after descending from the mountains deposit pebbles in a narrow belt of about 8 to 16 km in width lying parallel to the slopes of the Shivalik. It is known as Terai.

2. South of Terai, the streams and rivers re-emerge and create a wet, swampy and marshy region known as Bhabar.

3. The largest part of the northern plain is formed of older alluvium. They lie above the flood plains of the rivers and present a terrace-like feature. This part is known as Khadar.

4. The newer, younger deposits of the flood plants are called Bhangar.

Which of the statements given above is/are correct?

Solution:
  • According to the variations in relief features, the Northern plains can be divided into four regions.

  • After descending from the mountains, the rivers deposit pebbles in a narrow belt of about 8 to 16 km in width lying parallel to the slopes of the Shivalik.

  • It is known as bhabar. All the streams disappear in this bhabar belt. South of this belt, the streams and rivers re-emerge and create a wet, swampy and marshy region known as Terai. This was a thickly forested region full of wildlife.

The forests have been cleared to create agricultural land and to settle migrants from Pakistan after partition. Dudhwa National Park is located in this region.

The largest part of the northern plain is formed of older alluvium. They lie above the flood plains of the rivers and present a terrace-like feature. This part is known as bhangar. The soil in this region contains calcareous deposits locally known as kankar. The newer, younger deposits of the flood plains are called khadar. They are renewed almost every year and so are fertile, thus, ideal for intensive agriculture.

QUESTION: 4

Consider the following statements:

1. Bangar soils are less prone to floods.

2. Bangar soils are nothing but new alluvial soils.

3. Bangar soils are more fertile than Khadar soils.

4. Khadar plains are those that are low-lying next to a river.

Which of the above is/are incorrect?

Solution:
  • Khadir or Khadar plains are those that are low-lying next to a river. Khadir areas are prone to flooding and sometimes include portions of former river-beds that became available for agriculture when a river changed.

  •  

    Khadir soil consists of new alluvial deposits and is often very fertile. Bangar plains are more upland and consist of older alluvial soil. Bangar areas are less prone to flooding but are usually more sandy and less fertile as well.

 

 

 

QUESTION: 5

Regarding Terai region, consider the following statements:

1. It is a marshy, wet region at the foothills of Shivalik ranges.
