The correct answer is: Both (A) and (B).
Ladakh is a cold desert because of its location in the rain shadow of the Great Himalayas. The Himalayas block the moisture-laden winds from the Indian Ocean, preventing them from reaching Ladakh. This results in a very dry climate, with annual rainfall of only about 100 mm.
The high altitude of Ladakh also contributes to its cold climate. The average temperature in Ladakh is about -5°C, and it can get as cold as -40°C in winter.
The combination of low rainfall and high altitude makes Ladakh a cold desert.
Here is a brief explanation of each option:
- Option A: Location of Great Himalayas. The Himalayas block the moisture-laden winds from the Indian Ocean, preventing them from reaching Ladakh. This results in a very dry climate, with annual rainfall of only about 100 mm.
- Option B: Rain shadow area. The rain shadow effect is a phenomenon that occurs when moist air is forced to rise over a mountain range. As the air rises, it cools and condenses, forming clouds and rain. The air that descends on the other side of the mountain range is dry, as all of the moisture has been lost. Ladakh is located in the rain shadow of the Great Himalayas, which is why it is such a dry place.
- Option C: Both (A) and (B). The combination of low rainfall and high altitude makes Ladakh a cold desert.
