Question

The largest part of the northern plain is formed of: * Bhabar, Terai, Doab, Bhangar.

Answer 1

It is a 10-20 km wide marshy region in the south of Bhabar and runs parallel to it.

The Tarai is wider in the eastern parts of the Great Plains, especially in the Brahmaputra valley due to heavy rainfall.

It is characterized by the re-emergence of the underground streams of the Bhabar belt.

The reemerged water transforms large areas along the rivers into badly drained marshy lands.

Once covered with dense forests, most of the Tarai land (especially in Punjab, Uttar Pradesh and Uttarakhand) has been reclaimed and turned into agricultural land over a period of time.
