Agra and Darjeeling are located on the same latitude, but temperature of January in Agra is 16°C whereas it is only 4°C in Darjeeling. It is due to the altitude difference. Temperature decreases with height. Due to thin air, places in the mountains are cooler than places on the plains.

Meera Singh answered |
There is heavy rainfall on the western coast of India but very little in the Deccan because the Deccan plateau is situated in the rain shadow of the Western Ghats. The Deccan Plateau to the east of the Western Ghats receives significantly less rainfall than the coasts. As the summer (wet) monsoons approach the West Coast of India, they rise up the western Ghats (mountains) and the air cools. This cool air is less able to hold moisture and it is released as rainfall.

Shruti Joshi answered |
The most important geographical advantage of the Himalayas is option 3: They prevent the monsoons from crossing to the north and also serve as a reservoir of water from which our perennial rivers flow. The Himalayas act as a barrier to the southward movement of cold, dry winds from Central Asia and Siberia, which helps to maintain a relatively warm and humid climate in the Indian subcontinent. Moreover, the Himalayas receive heavy rainfall during the monsoon season, which results in the formation of numerous rivers and streams that provide water for irrigation, hydroelectric power generation, and other human needs.

- The standard meridian of India is 82°30' E longitude.
This statement is correct. 82°30' E is the standard meridian of India, passing through Mirzapur in Uttar Pradesh. - India’s coastline is the longest in the world.
This statement is incorrect. India has a coastline of about 7,516.6 km, but it is not the longest in the world. The longest coastline belongs to Canada. - The southernmost point of India is Kanniyakumari.
This statement is incorrect. The southernmost point of mainland India is Kanniyakumari, but the actual southernmost point of the entire territory of India is Indira Point, located in the Nicobar Islands. - India extends from 6°45' N latitude to 37°6' N latitude.
This statement is correct. India’s latitudinal extent is indeed from 6°45' N (southernmost point: Indira Point) to 37°6' N (northernmost point in Jammu and Kashmir).

Analysis of Statements
Let's evaluate each statement provided:

- This statement is false. The Tropic of Cancer lies at approximately 23.5° N latitude and passes through the central part of India, but not through the southernmost point, which is Kanyakumari.
2. Indian Standard Time (IST) is based on the 82°30' E longitude.
- This statement is true. IST is indeed based on the 82.5° E longitude, which is 5 hours and 30 minutes ahead of UTC (Coordinated Universal Time).

Earthquakes and volcanic eruptions that cause the sea-floor to move abruptly resulting in sudden displacement of ocean water in the form of high vertical waves are called tsunamis (harbour waves) or seismic sea waves. A tsunami is generated when an earthquake comes or a volcano erupts.

Prashanth Das answered |
The northeastern plateau is an extension of the main Peninsular plateau. It is believed that due to the force exerted by the northeastward movement of the Indian plate at the time of the Himalayan origin, a huge fault was created between the Rajmahal hills and the Meghalaya hills. Today, the Meghalaya and Karbi Anglong plateau stand detached from the main peninsular block.

Crafty Classes answered |
- Assertion (A) is true. Tsunamis, due to their wave characteristics and behavior, do indeed cause more significant damage when they reach shallow coastal waters rather than in the deep ocean.
- Reason (R) is also true. The speed of tsunami waves is affected by water depth; they travel faster in deeper water. However, this does not explain why they cause more destruction near the coast. Instead, the wave height increases as they approach shallower waters, which is the primary cause of coastal devastation.
- Therefore, while both statements are true, the reason provided does not correctly explain the assertion.

- Statement I is correct as India’s vast latitudinal extent does lead to diverse climatic conditions.
- Statement II is correct because the distance between longitudes indeed decreases towards the poles.
- Statement III is correct since the easternmost point of India experiences sunrise earlier than the westernmost point.
- Statement IV is incorrect as the Indian Standard Time (IST) is based on the 82°30' E longitude, not 68°7' E.

Rishabh Sengupta answered |
In winters, the northwestern parts of the subcontinent attracts wind from the Meditteranean region in the form of westerly disturbances. After September, retreating monsoons move out of the Ganga plains towards the low pressure zone of Bay of Bengal. They gather moisture from the bay and are drawn towards another low-pressure zone in the southern peninsula.

Athul Chawla answered |
The speed of wave in the ocean depends upon the depth of water. It is more in the shallow water than in the ocean deep. As a result of this, the impact of tsunami is less over the ocean and more near the coast where they cause large-scale devastations.

Chronological Order of Geographical Features in India
To understand the correct chronological order of the given geographical features of India, we can analyze each one based on its formation or significance in history.
1. Formation of the Himalayas
- The Himalayas began forming approximately 50 million years ago due to the collision of the Indian tectonic plate with the Eurasian plate.
- This geological event is significant as it shaped not only the physical landscape of northern India but also influenced climate patterns and the biodiversity of the region.
2. Development of the Ganga River System
- The Ganga River system developed over millions of years, with its origins traced back to the melting glaciers of the Himalayas.
- The river has been central to Indian civilization, providing water resources, supporting agriculture, and serving as a cultural and spiritual symbol for millions.
3. Recognition of India's Varied Ecosystems
- The varied ecosystems of India, including forests, grasslands, deserts, and coastal areas, have been recognized more prominently in the 20th century.
- This recognition has been vital for conservation efforts and understanding the ecological diversity of India.
4. Establishment of the Indian Standard Time
- Indian Standard Time (IST) was officially adopted in 1906.
- This was a significant milestone for coordinating time across the vast geographical expanse of India, reflecting the modernization of the country during British colonial rule.
Conclusion
Based on the above analysis, the correct chronological order is:
1. Formation of the Himalayas
2. Development of the Ganga River system
3. Recognition of India's varied ecosystems
4. Establishment of the Indian Standard Time
