GS Mains Questions and Answers

Q1: Explain the role of the Bhabar region in the geomorphology of northern India and its importance for groundwater recharge.

Answer: The Bhabar region, a narrow belt of coarse alluvium at the foothills of the Himalayas, plays a crucial role in the geomorphology of northern India. It acts as a transition zone between the mountainous areas and the plains. The region is significant for groundwater recharge, as the porous soil allows water from rivers to seep into the ground, replenishing aquifers. This natural process helps maintain the water table in nearby areas and prevents flooding in the plains by reducing the flow of surface water downstream.

Moreover, the Bhabar region serves as a buffer zone that absorbs seismic energy during earthquakes, providing some protection to the adjacent plains. Its unique physical characteristics make it an important feature in northern India's geography and hydrology.

Q2: Discuss the challenges posed by the Bhabar region for agriculture and settlement.

Answer: The Bhabar region poses significant challenges for agriculture and settlement due to its coarse, porous soil and the tendency of rivers to disappear into the ground. The lack of surface water makes irrigation difficult, and the soil’s texture is not conducive to retaining moisture, limiting agricultural productivity.

Furthermore, the region is prone to seismic activity due to its proximity to the Himalayas, making it less ideal for permanent settlements. The terrain is often uneven, and the risk of landslides during monsoons adds to the challenges. As a result, the Bhabar region is sparsely populated, with limited agricultural activity compared to the fertile Terai region further south.

Q3: Compare and contrast the geographical characteristics of the Bhabar and Terai regions, highlighting their roles in the hydrological cycle.

Answer: The Bhabar and Terai regions are distinct geographical zones located at the foothills of the Himalayas, with contrasting characteristics. The Bhabar region is characterized by coarse alluvial deposits and porous soil, where rivers disappear underground. This region plays a crucial role in groundwater recharge by allowing water to seep into aquifers.

In contrast, the Terai region is a marshy and waterlogged area located just south of the Bhabar zone. It is characterized by fertile soils and dense vegetation, as the underground streams from the Bhabar zone re-emerge here. The Terai is highly suitable for agriculture due to the availability of water and rich alluvial soil.

Both regions play vital roles in the hydrological cycle, with the Bhabar zone facilitating groundwater recharge and the Terai region acting as a zone of water retention and high agricultural productivity.

Previous Year Questions on Bhabar

1. UPSC CSE Prelims 2018:

Question: Which of the following is a feature of the Bhabar region?

A) Marshy land
B) Dense forests
C) Coarse alluvium
D) Black soil

Answer: C

Explanation: The Bhabar region is characterized by coarse alluvium, deposited by rivers flowing down from the Himalayas. This porous soil causes rivers to disappear underground, contributing to groundwater recharge.

2. UPSC CSE Mains 2019 (GS Paper 1):

Question: "The Bhabar and Terai regions play distinct roles in the geography and hydrology of northern India." Discuss.

Answer: The Bhabar and Terai regions are crucial geographical features at the foothills of the Himalayas. The Bhabar region, with its coarse alluvial deposits, serves as a groundwater recharge zone where rivers disappear into the ground. This porous landscape helps prevent floods in the plains and maintains groundwater levels. On the other hand, the Terai region is marshy and waterlogged, where the underground streams re-emerge, creating fertile soils ideal for agriculture. Together, these regions contribute to the unique hydrology and agricultural productivity of northern India.
