Chapter 16: Structure and Physiography — Online MCQ Test

Q: Which of the following is the oldest physiographic division of India?

Answer: B. The Peninsular Plateau — The Peninsular Plateau is made of some of the oldest rocks in India and is considered the oldest physiographic division. It is a stable landmass compared to the younger Himalayan region.

Q: The Himalayas were formed mainly due to the collision of which two plates?

Answer: A. Indian Plate and Eurasian Plate — The Himalayas were formed by the convergence and collision of the Indian Plate with the Eurasian Plate. This is a classic example of young fold mountain formation.

Q: The Himalayas are best described as:

Answer: B. A young fold mountain system — The Himalayas are young fold mountains formed by tectonic compression. Their peaks, deep valleys, and active geology reflect their youth.

The Himalayas are best described as:

A. A stable shield region
B. A young fold mountain system ✓
C. An old dissected plateau
D. An erosional plain

A. They are eroded into wide plains by wind action
B. They were formed from ancient igneous intrusions
C. They are still rising due to ongoing tectonic movements ✓
D. They are located in the interior of an old stable shield

Answer: C. They are still rising due to ongoing tectonic movements
The Himalayas are still tectonically active because the Indian Plate continues to move northward. This causes uplift, earthquakes and other geological activity.

Which of the following is the most appropriate reason for the high density of population in the Indo-Gangetic Plains?

A. Presence of mineral-rich hard rocks and steep slopes
B. Flat relief, fertile alluvium and good transport connectivity ✓
C. Extreme cold climate and sparse vegetation
D. Dominance of lava plateaus and narrow valleys

Answer: B. Flat relief, fertile alluvium and good transport connectivity
The Indo-Gangetic Plains support dense population because they offer fertile soil, level land and favourable conditions for agriculture, transport and settlement.
