The part of the Himalayas lying between the Satluj and Kali rivers is known by which regional name?

Introduction / Context:
This question is about the regional divisions of the Himalayan mountain system. Different stretches of the Himalayas between major rivers are given distinct regional names such as Punjab Himalaya, Kumaon Himalaya, and Nepal Himalaya. Knowing which name corresponds to which river segment is a standard requirement in Indian geography syllabi.

Given Data / Assumptions:

• The question focuses on the Himalayan segment between the Satluj and Kali rivers.
• The options are Punjab Himalaya, Nepal Himalayas, Kumaon Himalayas, Assam Himalayas, and Garhwal Himalayas.
• We assume the conventional classification that names segments based on important rivers acting as boundaries.
• The Kali river referred to here is the river that forms part of the boundary between India and Nepal.

Concept / Approach:
Geographers divide the Himalayas into river bounded segments for ease of description. The part between the Indus and Satluj rivers is often called the Punjab or western Himalaya. The stretch between the Satluj and Kali rivers is known as Kumaon Himalaya. Further east, between Kali and Tista, lies the Nepal Himalaya, and beyond that are the Assam or eastern Himalayas. Garhwal Himalaya is a more local term associated with part of the region within Uttarakhand but does not cover the entire Satluj to Kali segment by itself in the standard naming scheme.

Step-by-Step Solution:
Step 1: Recall the river based segmentation of the Himalayas into Indus Satluj, Satluj Kali, Kali Tista, and Tista Dihang sections. Step 2: Remember that the section between Indus and Satluj is usually called Punjab Himalaya. Step 3: Recall that the section between Satluj and Kali rivers is termed Kumaon Himalaya in most textbooks. Step 4: Note that Nepal Himalaya refers to the region between Kali and Tista, which lies further east than the section asked about. Step 5: Confirm that Kumaon Himalayas is the correct name for the Satluj to Kali segment and select it as the answer.

Verification / Alternative check:
You can verify this in standard Indian geography books where a table or map lists the divisions: Punjab Himalaya between Indus and Satluj, Kumaon Himalaya between Satluj and Kali, Nepal Himalaya between Kali and Tista, and Assam or eastern Himalaya east of Tista. The chapter on the Himalayas also mentions important peaks and holy places in the Kumaon region of Uttarakhand as lying within this Satluj Kali sector, confirming the label Kumaon Himalaya.

Why Other Options Are Wrong:
Punjab Himalaya corresponds to the stretch between the Indus and Satluj rivers, so it does not match the Satluj to Kali segment. Nepal Himalayas refer to the section between Kali and Tista, not Satluj and Kali. Assam Himalayas are further east and often associated with the easternmost Himalayan ranges in Arunachal Pradesh and adjoining areas. Garhwal Himalayas is a sub region within the western central Himalayas in Uttarakhand but in standard classification does not denote the entire Satluj to Kali river segment, which is labelled Kumaon Himalaya.

Common Pitfalls:
Learners often mix up Kumaon and Nepal Himalaya because both lie in the central part of the chain and share some cultural links. Another pitfall is to think of Garhwal and Kumaon only as administrative or cultural regions of Uttarakhand and not pay attention to the exact river boundaries quoted in the exam. A careful reading of textbook maps showing river boundaries and labels for Himalayan segments helps avoid these confusions.

Final Answer:
Kumaon Himalayas
