Question

IN WHAT WAYS INDO GANGETIC PLANE DIFFERENT FROM PENINSULAR PLATEAU?

Answer 1

Explanation:

Indo-Gangetic Plain

The Indo-Gangetic Plain is also known as Indus-Ganga and the North Indian River Plain. It lies between the great northern mountain and peninsular plateau and is formed by three major rivers - the Ganges, the Indus, the Brahmaputra and their tributaries. It covers a large area of about 7, 00,000 sq. km in Northern and Eastern India. The plain is divided into three sections;

a. The Punjab Plains - major portion this is in Pakistan; formed by Indus and its tributaries- Beas, Chenab, Jhelum, Ravi, and Sutlej.

b. Ganges Plains - Haryana, Delhi, UP, Bihar, parts of Jharkhand and West Bengal lie in the Ganga plains. This is formed by the Ganga and its tributaries. It is the largest part of the Northern Plains.

c. Bhramaputra Plains- lie mainly in Assam built by Brahmaputra and its tributaries.

The Northern plains can be divided into regions viz.-

The Bhabhar Belt: It is a narrow belt that lies in the foothills of Himalayas and comprises of pebbles and rocks brought down by the streams. Rivers flow at very fast speed in this region.

The Terai Belt: It is located next to the Bhabhar region and is made up of newer alluvium, rich for cultivation, has thick forests.

The Bangar Belt: It forms the higher part of the plains and is made of older alluvium soil which is less fertile. This region of the Gangetic plains is covered by Laterite soil, rich in iron and aluminium deposits.

The Khadar Belt It lies on the lowland areas beyond the Bangar belt and is made up of newer highly fertile alluvium brought down by the rivers. This region is flood prone.

• Roughly triangular in shape with its base coinciding with the southern edge of the great plain of North India. Apex of the triangular plateau is at Kanniyakumari.
• It covers a total area of about 16 lakh sq km (India as a whole is 32 lakh sq km).
• The average height of the plateau is 600-900 m above sea level (varies from region to region).
• Most of the peninsular rivers flow west to east indicating it’s general slope.
• Narmada-Tapti are the exceptions which flow from east to west in a rift (rift is caused by divergent boundary (Go back to Interaction of plates).
