• B. Terai
• C. Bhangar
• D. Khadar

Answer 1

Answer:

B. Terai

the physiographic feature of the North Indian plain where the Himalayan rivers re-emerge is called the Terai.

The Terai is a region of wet, marshy, and forested land lying to the south of the Himalayas. It is characterized by saline marshes, swamps, and high groundwater tables. The region is formed by the alluvial deposits brought by the rivers originating from the Himalayas.

The Himalayan rivers, such as the Ganga, Yamuna, Ghaghara, and others, once they descend from the mountains and reach the foothills, re-emerge in the Terai region. Here, they spread out and form channels, contributing to the high fertility of the land. The Terai is often considered part of the Gangetic Plain, but it is distinct because of its unique ecological and hydrological characteristics.

The Terai region is crucial for agriculture due to its fertile soil and availability of water. It also plays a vital role in maintaining the water table in the surrounding regions.
