Page 2 – Himalayan Mountain System
Model Questions & Answers (Q21–40)
Q21. Explain the origin of the Himalayan mountain system.
Answer: The Himalayas were formed due to the collision between the Indian Plate and the Eurasian Plate during the Tertiary period. The closure of the Tethys Sea and subsequent compressional forces resulted in folding and upliftment.

Q22. Discuss the longitudinal divisions of the Himalayas.
Answer: The Himalayas are divided into Himadri (Greater Himalayas), Himachal (Lesser Himalayas), and Shiwaliks (Outer Himalayas), based on height, structure, and composition.

Q23. Differentiate between Western and Eastern Himalayas.
Answer: Western Himalayas are broader with extensive glaciers (Karakoram, Ladakh), while Eastern Himalayas are narrower, receive heavy rainfall, and are biodiversity-rich.

Q24. Explain the concept of syntaxial bends in the Himalayas.
Answer: Syntaxial bends occur where mountain ranges abruptly change direction. In India, Nanga Parbat (west) and Namcha Barwa (east) mark these bends.

Q26. Analyse the role of Himalayas in Indian climate.
Answer: The Himalayas block cold Central Asian winds and intercept monsoon winds, causing heavy rainfall in northern and northeastern India.
Answer: The Himalayas block cold Central Asian winds and intercept monsoon winds, causing heavy rainfall in northern and northeastern India.
Q27. Explain the formation of Himalayan glaciers.
Answer: Glaciers form due to accumulation and compaction of snow in high-altitude regions. Examples include Siachen and Gangotri glaciers.
Answer: Glaciers form due to accumulation and compaction of snow in high-altitude regions. Examples include Siachen and Gangotri glaciers.
Q28. Discuss seismic vulnerability of the Himalayan region.
Answer: Being tectonically active, the Himalayas fall under high seismic zones (Zone IV & V). Earthquakes are frequent due to plate movement.
Answer: Being tectonically active, the Himalayas fall under high seismic zones (Zone IV & V). Earthquakes are frequent due to plate movement.
