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.

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.

Peninsular region of India dominated by denuded rocks
The peninsular region of India is dominated by denuded rocks. Let's understand this in detail.
What is the peninsular region of India?
The peninsular region of India comprises the Deccan Plateau and the adjoining mountain ranges. The Deccan Plateau is a large plateau that occupies most of the southern part of India. It is bounded by the Eastern Ghats in the east, the Western Ghats in the west, and the Satpura Range in the north.
What are denuded rocks?
Denuded rocks are rocks that have been exposed to weathering, erosion, and other natural processes that have caused them to lose their original surface features. These rocks are often characterized by a smooth, rounded surface that is the result of the action of wind, water, and other natural forces.
Why is the peninsular region of India dominated by denuded rocks?
The peninsular region of India has a long geological history that has resulted in the formation of a variety of rock types. Over time, these rocks have been exposed to weathering and erosion, which has caused them to lose their original surface features and become denuded. The region is also characterized by a relatively dry climate, which has further contributed to the denudation of the rocks.
Conclusion
In conclusion, the peninsular region of India is dominated by denuded rocks due to its long geological history, exposure to weathering and erosion, and relatively dry climate.
