Question 1

1. India's latitudinal extent is approximately $30^\circ$. If the Sun rises in Arunachal Pradesh ($97^\circ 25' E$) at 5:00 AM, approximately what time would it rise in Jaisalmer ($68^\circ 7' E$) due to the longitudinal difference?

A) 5:00 AMB) 7:00 AMC) 6:00 AMD) 4:00 AM

Answer

✓ Correct Answer: Option B

Explanation: The longitudinal difference is approx $97^\circ - 68^\circ = 29^\circ$. Since $1^\circ$ of longitude corresponds to a 4-minute time difference, $29^\circ \times 4 mins = 116 mins \approx 2 hours$. Since the East rises first, Jaisalmer (West) will see the sun approx 2 hours later: 5:00 AM + 2 hours = 7:00 AM.

Question 2

2. The Northern Plains of India are formed by the interplay of three major river systems. Which of the following represents the correct set?

A) Ganga, Yamuna, Godavari Indus, Narmada, Tapti

Question 3

3. The Deccan Plateau is a triangular landmass that lies to the south of the river Narmada. It is higher in the and slopes gently .

A) West, EastwardsB) East, WestwardsC) North, SouthwardsD) South, Northwards

Answer

✓ Correct Answer: Option A

Explanation: The Peninsular plateau is higher in the west and slopes gently eastwards. This is evidenced by the fact that most major rivers (Godavari, Krishna, Kaveri) flow from West to East into the Bay of Bengal.

Question 4

4. Mawsynram, located in the Khasi Hills, receives the highest average rainfall in the world (11,871 mm). This is primarily due to:

A) Its proximity to the Thar DesertB) The influence of the Western GhatsC) The cold winds from SiberiaD) The funnel shape of the Khasi Hills

Answer

✓ Correct Answer: Option D

Explanation: The Khasi Hills have a funnel shape which traps the moisture-laden monsoon winds from the Bay of Bengal, forcing them to rise rapidly and cause heavy orographic rainfall.

Question 5

5. Identify the feature: It is a narrow belt about 8 to 16 km in width lying parallel to the slopes of the Shiwaliks where rivers deposit pebbles.

A) TeraiB) BhabarC) KhadarD) Bhangar

Answer

✓ Correct Answer: Option B

Explanation: The rivers, after descending from the mountains, deposit pebbles in a narrow belt of about 8 to 16 km in width known as <b>Bhabar</b>.

Question 6

6. The Lakshadweep Islands are known as ________ islands because they are formed from the skeletal remains of tiny marine organisms.

A) VolcanicB) TectonicC) CoralD) Sedimentary

Answer

✓ Correct Answer: Option C

Explanation: Lakshadweep islands are small coral islands. Corals are short-lived microscopic organisms (polyps) whose skeletons accumulate to form coral islands.

Question 7

7. Which mountain range acts as a climatic barrier, preventing the cold Central Asian winds from entering the Indian subcontinent?

A) The HimalayasB) The AravalisC) The VindhyasD) The Satpuras

Answer

✓ Correct Answer: Option A

Explanation: The Himalayas act as a giant wall that blocks the cold, dry winds from Central Asia and also traps the monsoon winds within the subcontinent.

Question 8

8. The Western Coastal Plain is ________ than the Eastern Coastal Plain.

A) Much widerB) Higher in elevationC) The same widthD) Narrower

Answer

✓ Correct Answer: Option D

Explanation: The Western Coastal Plain is a narrow strip sandwiched between the Western Ghats and the Arabian Sea, whereas the Eastern Coastal Plain is wider and level.

Question 9

9. If a traveler moves from the equator ($0^\circ$) towards the North Pole ($90^\circ N$), the diversity of flora and fauna generally:

A) IncreasesB) DecreasesC) Remains constantD) First decreases then increases

Answer

✓ Correct Answer: Option B

Explanation: Biodiversity is highest in the tropical regions near the equator due to abundant sunlight and rainfall, and it generally decreases as we move towards the poles.

Question 10

10. The 'Standard Meridian of India' ($82^\circ 30' E$) passes through which city, serving as the basis for Indian Standard Time (IST)?

A) New DelhiB) MumbaiC) Mirzapur (UP)D) Kolkata

Answer

✓ Correct Answer: Option C

Explanation: The Standard Meridian of India ($82^\circ 30' E$) passing through Mirzapur in Uttar Pradesh is taken as the standard time for the whole country.

Accepted Answer

✓ Correct Answer: Option C

Explanation: The Northern Plains (Indo-Gangetic-Brahmaputra plains) are formed by the alluvial deposits of the Indus, the Ganga, and the Brahmaputra along with their tributaries.
