Question

The Punjab and the Haryana plains are bounded by _____________ in the North.
(A) Shiwalik ranges
(B) Rajasthan ranges
(C) Delhi ranges
(D) None of these

Answer 1

Hint: The Punjab and Haryana plain constitute a vast alluvial plain in Eastern Pakistan and Northwestern India. The alluvial plain facilitates agricultural cultivation in these areas and thus these states are the major agricultural states of India.

Complete answer:
Starting from the Indus to the Brahmaputra, these Mountain ranges run in a west to east direction. Many valleys lie in between these ranges. The ‘Himadri’ or the Great or Inner Himalayas is the northernmost range. The average altitude of this range is 6,000 meters. All the prominent peaks lie in this range and its core is composed of granite.
The Himachal or lesser Himalaya is the next range. It forms the most rugged mountain system and lies to the south of the Himadri. It is composed majorly of highly altered and compressed rocks and its height ranges from 3,700 to 4,500 meters. Although Dhaula Dar and Mahabharat ranges are also important ranges, the Panjal range is the longest and most prominent one. This range is well known for its hill stations and it is home to the famous Kullu valley in Himachal Pradesh and the Kashmir valley.
Shiwaliks are known as the outermost range of the Himalayas. The Punjab and Haryana plains are bounded by these ranges. The unconsolidated sediments brought down by rivers from the main Himalayan ranges compose these ranges and thus these valleys are covered with alluvium and thick gravel and extend over a width of 10-50 Km and have a height varying between 900 and 1100 meters.

Thus, option (C) is correct.

Note: The Shiwaliks also constitute Duns. These are the longitudinal valleys lying between the Shiwaliks and the lesser Himalayas.
