Question 5

Which of the following is the largest plateau in India?

Accepted Answer

The Deccan Plateau is the largest plateau in India, covering an area of approximately 500,000 square kilometers. It is located in southern India and is bounded by the Western Ghats on the west and the Eastern Ghats on the east.

Question 6

The Deccan Plateau is bounded by which two mountain ranges on its western and eastern sides?

Accepted Answer

The Deccan Plateau is bounded by the Western Ghats on its western side and the Eastern Ghats on its eastern side. The Western Ghats run along the western coast of India (from Gujarat to Kerala) and are higher in elevation, while the Eastern Ghats run along the eastern coast (from Odisha to Tamil Nadu) and are lower in elevation.

Question 7

Which soil type is most commonly found in the Indo-Gangetic Plain and is formed by the deposition of fine sediments by rivers?

Accepted Answer

Alluvial soil is the most common soil type in the Indo-Gangetic Plain. It is formed by the deposition of fine sediments (silt, clay, and sand) carried by rivers during floods. This soil is highly fertile and supports intensive agriculture, making it one of the most productive agricultural regions in India.

Question 8

The Narmada River, one of India's major rivers, flows in which direction before emptying into the Arabian Sea?

Accepted Answer

The Narmada River flows from east to west across central India. It originates in the Amarkantak Plateau in Madhya Pradesh and flows westward through the Narmada Valley (a rift valley) before emptying into the Arabian Sea in Gujarat. It is one of the few major Indian rivers that flows from east to west.

Question 9

Which of the following mountain passes connects India with China and is located in the eastern Himalayas?

Accepted Answer

The Nathu La Pass is a major mountain pass in the eastern Himalayas that connects India (Sikkim) with China (Tibet). It is located at an elevation of 4,330 meters and was reopened for trade in 2006 after remaining closed for 44 years following the 1962 Sino-Indian War. It is one of the oldest trade routes between India and Tibet.

Question 10

Which of the following rivers originates from the Western Ghats and flows eastward across the Deccan Plateau, forming the second-longest river system in peninsular India after the Godavari?

Accepted Answer

The Krishna River originates from the Western Ghats near Mahabaleshwar in Maharashtra at an elevation of approximately 1,338 meters. It flows eastward across the Deccan Plateau for about 1,400 km before emptying into the Bay of Bengal in Andhra Pradesh. It is the second-longest river in peninsular India after the Godavari (1,465 km). Major tributaries include the Tungabhadra, Bhima, and Koyna rivers.

Question 11

The Narmada River, which forms a natural boundary between North and South India, originates from the Amarkantak Plateau and flows westward. Which of the following statements about the Narmada is INCORRECT?

Accepted Answer

The Narmada River is approximately 1,312 km long and originates from the Amarkantak Plateau in Madhya Pradesh at an elevation of about 1,057 meters. It flows westward through a rift valley and empties into the Arabian Sea in Gujarat. The Narmada does NOT form a natural boundary between North and South India in the strict geographical sense—this is a common misconception. The actual boundary is more conventionally marked by the Vindhya and Satpura ranges. The Narmada flows between these ranges but does not serve as the primary North-South dividing line. The river has major tributaries including the Hiran, Burhner, Tawa, and Shakkar.

Question 12

The Brahmaputra River, one of Asia's major rivers, originates from the Chemayungdung Peak in the Kailash Range of the Tibetan Plateau. After flowing through Tibet, Arunachal Pradesh, and Assam, it joins the Ganges River to form the world's largest delta. What is the approximate length of the Brahmaputra River?

Accepted Answer

The Brahmaputra River is approximately 2,900 km long, making it one of the longest rivers in Asia. It originates from the Chemayungdung Peak (also called Kailash Peak) in the Kailash Range of the Tibetan Plateau at an elevation of approximately 5,150 meters. The river flows eastward through Tibet (where it is called Tsangpo), then enters Arunachal Pradesh and flows through Assam before joining the Ganges River in Bangladesh to form the Sundarbans Delta—the world's largest delta. The Brahmaputra has a drainage basin of approximately 580,000 square kilometers and is known for its high discharge rate and seasonal flooding.

Question 13

Which of the following mountain passes in the Himalayas connects the Spiti Valley in Himachal Pradesh with the Kinnaur region and is located at an elevation of approximately 4,270 meters, making it one of the highest motorable passes in India?

Accepted Answer

The Kunzum Pass (also spelled Kunzum La) is located at an elevation of approximately 4,270 meters and connects the Spiti Valley with the Kinnaur region in Himachal Pradesh. It is one of the highest motorable passes in India and serves as a crucial link between the cold desert region of Spiti and the Kinnaur district. The pass is typically open from June to September due to heavy snowfall during winter months. Other notable high passes in the region include Rohtang Pass (3,978 m), Baralacha La (4,890 m), and Tanglang La (5,328 m in Ladakh).

Question 14

The Narmada River, one of India's major peninsular rivers, originates from the Amarkantak Plateau in Madhya Pradesh and flows westward into the Arabian Sea. Which of the following statements about the Narmada River is INCORRECT?

Accepted Answer

The Narmada River is approximately 1,312 km long, originates in Amarkantak (Madhya Pradesh), flows through Madhya Pradesh and Gujarat, and forms the boundary between Madhya Pradesh and Maharashtra for a significant stretch. It is one of only two major rivers in peninsular India that flows from east to west (the other being the Tapti). The river does NOT form the boundary between Gujarat and Rajasthan; it forms the boundary between Madhya Pradesh and Maharashtra, and later between Madhya Pradesh and Gujarat.
