Shivalik Hills Geographical Extent Explained

The Shivalik Hills, also known as the Outer Himalayas, represent the youngest and southernmost mountain range of the great Himalayas. They are primarily composed of sedimentary rocks, often unconsolidated, which contributes to their characteristic lower altitudes and susceptibility to erosion compared to the higher Himalayan ranges.

Understanding the Shivalik Hills' Location

These hills form the foothills of the Himalayas and stretch across a significant portion of Northern India. Their formation is a result of the ongoing collision between the Indian and Eurasian tectonic plates.

Key Geographical Spread:

• The Shivalik Hills begin in the northwestern part of India in the union territory of Jammu and Kashmir.
• They continue eastward through states like Himachal Pradesh, Punjab, and Haryana.
• The range extends significantly into the northern Indian state of Uttarakhand.

Analyzing the Options Provided

Let's evaluate the given options based on the known geographical distribution of the Shivalik Hills:

• Option 1: Punjab to Sikkim - While the Shivalik Hills do extend through Punjab, they do not reach Sikkim, which lies in the Eastern Himalayas.
• Option 2: Bihar to West Bengal - These states are located east of the main Shivalik range's extent, although parts of the Bihar and West Bengal foothills share some characteristics. However, the primary range does not start or prominently feature here.
• Option 3: Jammu and Kashmir to Uttarakhand - This option accurately captures the western and eastern termini of the main Shivalik range within India. It covers the continuation from the northwest towards the central Himalayan region.
• Option 4: Arunachal Pradesh to Manipur - These states are located in the far northeastern part of India and constitute the Eastern Himalayas, which are distinct from the Shivalik range.

Therefore, the most accurate description of the extent of the Shivalik Hills across Indian states is from Jammu and Kashmir to Uttarakhand.
