Question

Which is the most fertile region of India?
A) The Himalayas
B) The central highlands
C) The Indo-Gangetic plain
D) Peninsular plateau

Answer 1

Hint: It is the world's largest continuous stretch of alluvium, formed by the deposition of sediment by various rivers. The plains are flat and mainly treeless, making canal irrigation a viable option. The area also has a lot of underground water sources. The plains are the most intensively farmed areas on the planet. Rice and wheat are the principal crops farmed, and they are rotated.

Complete answer:
The Indo-Gangetic plains, commonly known as the Indus Ganga and the North Indian river plain, is a rich plain spanning most of northern and eastern India, covering 255 million hectares (630 million acres).
The region is named after the rivers Indus and Ganges and includes a number of significant cities. The Himalayas, which feed the plain's numerous rivers and are the source of the fertile alluvium deposited throughout the region by the two river systems, border it on the north. The Chota Nagpur Plateau marks the plain's southern boundary.

The Delhi Ridge divides the Indo-Gangetic Plain into two drainage basins: the western part drains to the Indus, while the eastern part contains the Ganga–Brahmaputra drainage systems. Because the Indo-Gangetic Plain appears to be continuous from Sindh in the west to Bengal and Assam in the east, this divide is only 350 metres above sea level.

The fertile Terai area stretches over Southern Nepal and Northern India, running parallel to the Himalayan foothills. The Beas, the Chambal, the Chenab, the Ganga, the Gomti, the Indus, the Ravi, the Sutlej, and the Yamuna are among the rivers covered. The plain's salt-rich soil makes it one of the world's most intensively farmed locations. Even rural areas are thickly occupied in this city.

The correct option is C. The Indo-Gangetic plain is the most fertile region of India.

Note: The Indus and Ganges' numerous tributaries divide the plain into doabs or land tongues that extend to where the tributaries meet. Near the rivers lies khadar land, which is made up of young alluvium and is prone to floods. Bangar land is older alluvium deposited in the middle Pleistocene above the flood boundary.
