1. Question
The Himalayan mountains were formed as a result of which of the following processes?
CorrectAnswer: (b) Continental-continental convergence
Explanation:
• The Himalayas formed when the Indian Plate collided with the Eurasian Plate around 50 million years ago.
• Both plates are continental plates (no oceanic plate involved), and their collision caused the land to crumple and rise, forming the massive mountain range we see today.
• This is a classic example of continent-continent convergenceIncorrectAnswer: (b) Continental-continental convergence
Explanation:
• The Himalayas formed when the Indian Plate collided with the Eurasian Plate around 50 million years ago.
• Both plates are continental plates (no oceanic plate involved), and their collision caused the land to crumple and rise, forming the massive mountain range we see today.
• This is a classic example of continent-continent convergence - Question 2 of 5
2. Question
Consider the following
Assertion (A): Shiwaliks are known for rich deposits of fossils of prehistoric mammals.
Reason (R): Shiwaliks are the oldest part of the Himalayas.
Choose the correct answer:CorrectAnswer: (c) A is true, but R is false
Explanation:
• Assertion is correct: Shiwaliks are indeed rich in fossils of prehistoric mammals (because they formed by the deposition of river-borne materials that trapped these fossils).
• Reason is incorrect: Shiwaliks are the youngest part of the Himalayas, not the oldest.
• The Greater Himalayas (Himadri) are the oldest geological formation, while Shiwaliks formed much later (about 2–20 million years ago).IncorrectAnswer: (c) A is true, but R is false
Explanation:
• Assertion is correct: Shiwaliks are indeed rich in fossils of prehistoric mammals (because they formed by the deposition of river-borne materials that trapped these fossils).
• Reason is incorrect: Shiwaliks are the youngest part of the Himalayas, not the oldest.
• The Greater Himalayas (Himadri) are the oldest geological formation, while Shiwaliks formed much later (about 2–20 million years ago). - Question 3 of 5
3. Question
Consider the following statements:
1. The Purvanchal Hills lie along the India-Myanmar border.
2. The Karakoram range is part of the Greater Himalayas.
Which of the above statements is/are correct?CorrectAnswer: (a) 1 only
Explanation:
• Statement 1 is correct: The Purvanchal Hills (Patkai, Naga, Mizo Hills) are indeed located along the India-Myanmar border.
• Statement 2 is incorrect:
◦ The Karakoram range is part of the Trans-Himalayas, not the Greater Himalayas.
◦ Greater Himalayas include peaks like Mount Everest, Kanchenjunga, etc., whereas Karakoram includes K2.IncorrectAnswer: (a) 1 only
Explanation:
• Statement 1 is correct: The Purvanchal Hills (Patkai, Naga, Mizo Hills) are indeed located along the India-Myanmar border.
• Statement 2 is incorrect:
◦ The Karakoram range is part of the Trans-Himalayas, not the Greater Himalayas.
◦ Greater Himalayas include peaks like Mount Everest, Kanchenjunga, etc., whereas Karakoram includes K2. - Question 4 of 5
4. Question
The Eastern Syntaxial Bend is associated with which of the following locations?
CorrectAnswer: (c) Namche Barwa
Explanation:
• Syntaxial bends are points where the Himalayan arc sharply bends northward.
• Eastern Syntaxial Bend occurs near Namche Barwa (where the Brahmaputra river takes a dramatic U-turn).
• Western Syntaxial Bend occurs near Nanga Parbat (Indus gorge).IncorrectAnswer: (c) Namche Barwa
Explanation:
• Syntaxial bends are points where the Himalayan arc sharply bends northward.
• Eastern Syntaxial Bend occurs near Namche Barwa (where the Brahmaputra river takes a dramatic U-turn).
• Western Syntaxial Bend occurs near Nanga Parbat (Indus gorge). - Question 5 of 5
5. Question
Arrange the following Himalayan divisions in the order of their geological formation (oldest to youngest):
1. Greater Himalayas
2. Lesser Himalayas
3. Shiwaliks
Choose the correct sequence:CorrectAnswer: (a) 1-2-3
Explanation:
• Oldest: Greater Himalayas (formed first during initial plate collision).
• Then: Lesser Himalayas (formed due to later tectonic activities).
• Youngest: Shiwaliks (formed from erosion deposits of the above two).
Thus, the correct sequence is Greater Himalayas → Lesser Himalayas → Shiwaliks.IncorrectAnswer: (a) 1-2-3
Explanation:
• Oldest: Greater Himalayas (formed first during initial plate collision).
• Then: Lesser Himalayas (formed due to later tectonic activities).
• Youngest: Shiwaliks (formed from erosion deposits of the above two).
Thus, the correct sequence is Greater Himalayas → Lesser Himalayas → Shiwaliks.
