The Himalayan Mountains

The Shiwalik Range is the southernmost and outermost range of the Himalayas; therefore, it is called the Outer Himalaya. Himadri is the highest Great Himalayan range, while Himachal is known as the Lesser or Middle Himalaya. Exam tip: remember the north-to-south order—Himadri, Himachal, Shiwalik.

After the bend of the Brahmaputra in the east, the hills are called Purvachal. Exam tip: connect eastern hills with Purvachal.

Naga Hills are part of the Purvachal. Exam tip: connect Naga, Manipur and Mizo hills with Purvachal.

Mizo Hills are associated with the Purvachal region. Exam tip: connect Mizo Hills with India's northeast.

Thar is a desert, not a main Himalayan range. Exam tip: remember the three names Himadri, Himachal and Shiwalik.

The direct answer is B: Shiwalik is the low outer Himalayan range. To understand the comparison, arrange the main ranges from north to south: Himadri is the highest inner range; Himachal is the middle range; Shiwalik is the outer range nearest the Northern Plains and has the lowest general elevation. Therefore B is correct. A, Himadri, is the highest and most continuous range, so it is the opposite of the clue “low outer range.” C, Himachal, is the middle range and is higher than Shiwalik, so it is not the best answer. D, Great Himalaya, is another name for Himadri, not the low outer range. A common mistake is to treat all Himalayan ranges as equally high. Memory cue: Shiwalik = southernmost, outermost and lowest.

Many famous hill stations are located in Himachal or Lesser Himalaya. Exam tip: remember Lesser Himalaya for hill station clues.

Himadri, Himachal and Shiwalik are the three main Himalayan ranges. Exam tip: remember them with order.

The correct answer is C, the Thar Desert. Himadri, Himachal, and Shiwalik are the three parallel divisions commonly used to describe the Himalayan ranges. Himadri is the Great or innermost Himalayan range, Himachal is the Middle or Lesser Himalaya, and Shiwalik is the outer range. The Thar Desert belongs to the Indian Desert physiographic division in north-western India, not to the Himalayan mountain system. A, B, and D are therefore directly related to Himalayan structure. To answer a “not related” question, classify each option before considering its exact location. Three choices name Himalayan ranges, while one names a desert region. Common confusion: Himachal in this context means a Himalayan range; it is not being used here as the name of the state alone.

The Himalayas are a major mountain system along the northern part of India. They are made up of high, rugged ranges and deep valleys, so they clearly represent the mountain region or mountainous division of India. Hence, option A is correct. Their physical character is very different from that of deserts, islands, or coastal plains.

The question asks for the broad physical feature represented by the Himalayas, not for a detailed subdivision of the range. The Himalayas are formed by high relief, steep slopes, and great elevations, all of which are typical features of a mountain region. A desert is identified by dry sandy conditions, an island is land surrounded by water, and a coastal region lies near the sea. These descriptions do not match the Himalayas. Therefore, the correct classification is the mountain region.

From north to south, Himadri, Himachal and Shiwalik is the easy order. Exam tip: write the ranges in this order.
