The correct option is (c).
Explanation
The Northern Plains are divided into four regions based on the variations in relief features: Bhabar, Terai, Bhangar, and Khadar. The Bhabar belt represents the northernmost section of the plains, characterized by the deposition of coarse alluvial material.
Statement-wise Analysis:
- Statement 1 is Correct: The Bhabar is a narrow belt ranging between 8 to 16 km in width. It is formed by rivers descending from the mountains, which deposit heavy materials like pebbles and rocks in this zone.
- Statement 2 is Incorrect: The Bhabar belt lies parallel to the slopes of the Shiwaliks (the Outer Himalayas), not the Himadri (the Great Himalayas). It is located at the break of the slope where the rivers leave the mountainous region and enter the plains.
- Statement 3 is Correct: Due to the high porosity of the pebble-studded rock beds, all streams disappear in this belt and flow underground. These streams re-emerge in the swampy and marshy region known as the Terai, located south of the Bhabar.
Key Takeaway:
The Bhabar belt is a porous, pebble-rich zone located at the foot of the Shiwaliks where streams disappear underground, distinguishing it from the marshy Terai region to its south.
