Q1. With reference to the Himalayan mountain system, consider the following statements:
- The Himalayas are classified as young fold mountains.
- They were formed due to the collision of the Indian Plate with the Eurasian Plate.
- The Himalayan region is geologically stable compared to the Peninsular Plateau.
Which of the statements given above are correct?
A. 1 and 2 only
B. 2 and 3 only
C. 1 and 3 only
D. 1, 2 and 3
Correct Answer: A
Explanation:
Statements 1 and 2 are correct. The Himalayas are young fold mountains formed by plate collision. Statement 3 is incorrect; the Himalayas are geologically unstable and seismically active.
Q2. Arrange the following Himalayan ranges from south to north:
- Himadri
- Himachal
- Shiwalik
Select the correct sequence using the code below:
A. 1–2–3
B. 3–2–1
C. 2–1–3
D. 3–1–2
Correct Answer: B

Indus and Brahmaputra are antecedent rivers that cut deep gorges. The Ganga emerges after the Himalayas and does not cut a gorge across them.
Q4. The Main Central Thrust (MCT) is best described as:
A. Boundary between Shiwalik and Himachal ranges
B. Boundary between Himachal and Himadri ranges
C. Boundary between Peninsular Plateau and Himalayas
D. Zone of volcanic activity in the Himalayas
Correct Answer: B
Explanation:
The MCT separates the Lesser Himalayas (Himachal) from the Greater Himalayas (Himadri) and is tectonically very active.
Q5. Consider the following statements about the Shiwalik Range:
- It is composed mainly of unconsolidated sediments.
- It is the youngest part of the Himalayas.
- It has the highest average elevation among Himalayan ranges.
Which of the statements given above are correct?
A. 1 and 2 only
B. 2 and 3 only
C. 1 and 3 only
D. 1, 2 and 3
Correct Answer: A
