  • d)
    vulnerable species
Correct answer is option 'B'. Can you explain this answer?

Anjana Sharma answered
The Chiru, also known as the Tibetan antelope, is an endangered species. Let's understand why:

Endangered Species:
An endangered species is a species of animal or plant that is in danger of becoming extinct. A species can become endangered for various reasons, including habitat loss, poaching, and climate change.

Reasons for Endangerment of Chiru:
1. Habitat Loss: The Chiru inhabits the high-altitude grasslands and shrublands of the Tibetan Plateau and surrounding areas. However, human activities such as mining, grazing, and infrastructure development have led to habitat loss and fragmentation, which threatens the survival of the Chiru.

2. Poaching: The Chiru is hunted for its soft and warm wool, which is known as shahtoosh. Shahtoosh shawls are highly valued and can fetch high prices in the black market. Poaching of Chiru for shahtoosh has led to a significant decline in their population.

3. Climate Change: Climate change is also a threat to the Chiru. Changes in temperature and precipitation patterns can affect the availability of food and water, which can impact the survival of the Chiru.

Conservation Efforts:
To conserve the Chiru, various conservation efforts have been undertaken. These include:

1. Habitat Protection: Protected areas have been established to conserve the habitat of the Chiru. These areas are managed to reduce human impacts and preserve the natural ecosystem.

2. Anti-Poaching Measures: Efforts are being made to reduce poaching of Chiru for shahtoosh. This includes stricter enforcement of laws, awareness campaigns, and alternative livelihood options for local communities.

3. Climate Change Mitigation: Efforts are being made to reduce greenhouse gas emissions and mitigate the impacts of climate change. This includes promoting clean energy, sustainable land use practices, and adaptation measures.

Conclusion:
The Chiru is an endangered species due to habitat loss, poaching, and climate change. However, conservation efforts are underway to protect and conserve this species for future generations.

  • Deflation: This involves the lifting and blowing away of loose materials from the ground. Such unconsolidated sands and pebbles may be carried in the air or rolled along the ground depending on the grain size.
  • The finer dust and sands may be removed miles away from their place of origin, and be deposited even outside the desert margins. Deflation results in the lowering of the land surface to form large depressions called deflation hollows. The Qattara Depression of the Sahara Desert lies almost 450 feet below sea level.

The climate of the Ladakh desert is extremely cold and dry due to its high altitude which varies from about 3,000 m in Kargil to more than 8,000 m in Karakoram. The air at this altitude is so thin that the heat of the sun can be felt intensely. The day temperatures in summer are just above zero degrees and the night temperatures are below -30C. Winters are extremely cold with temperatures below -40C most of the time. There is very little rainfall in this region. It is as low as 10 cm every year. The area experiences freezing winds and burning hot sunlight. There is always a chance of sunstroke and frostbite at the same time.

    Teeth
  • b)
    Eyes
  • c)
    Skin
  • d)
    Hair
Correct answer is option 'D'. Can you explain this answer?

Rajesh Khatri answered
- Wool comes from sheep, goat, yak and some other animals. These wool-yielding animals bear hair on their body because hair keeps these animals warm and wool is derived from these hairy fibres.
- The hairy skin of the sheep has two types of fibres that form its fleece:
(i) the coarse beard hair, and
(ii) the fine soft under-hair close to the skin. 
- Some breeds of sheeppossess only fine under-hair. Theirparents are specially chosen to give birthto sheep which have only soft under hair.This process of selecting parentsfor obtaining special characters in theiroffspring, such as soft under hair insheep, is termed ‘selective breeding’.

Correct answer is option 'D'. Can you explain this answer?

Jatin Ghosh answered
  • Zeugen: These are tabular masses with a layer of soft rocks lying beneath a surface layer of more resistant rocks. The sculpting effects of wind abrasion wear them into a weird-looking 'ridge and furrow landscape.
  • Mechanical weathering initiates their formation by opening up joints of the surface rocks. Wind abrasion further eats' into the under Irving softer layer so that deep furrows are developed.
  • The hard rocks then stand above the furrows as ridges or Eugen and many even overhang. Such tabular blocks of zeugen may stand 10 to 100 feet above the sunken furrows. Continuous abrasion by wind gradually lowers the zeugen and widens the furrows.

Ladakh lies in the rain shadow of
  • a)
    Aravali
  • b)
    Alps
  • c)
    Himalaya
  • d)
    Kanchenjunga
Correct answer is option 'C'. Can you explain this answer?

Preethi Ahuja answered
Ladakh lies in the rain shadow of the Himalaya.

Explanation:
- The rain shadow effect occurs when there is a mountain range that blocks the passage of rain-bearing clouds, thereby creating a dry region on the leeward side.
- In the case of Ladakh, it lies on the northern side of the Himalayan mountain range, which acts as a barrier for the monsoon winds coming from the south.
- The monsoon winds carry moisture from the Indian Ocean and bring rainfall to the southern slopes of the Himalayas and the Indian subcontinent.
- As these winds rise and reach the southern slopes of the Himalayas, they cool down and release moisture, resulting in heavy rainfall in regions like Uttarakhand and Himachal Pradesh.
- However, as the winds continue to move northwards and reach the northern side of the Himalayas, they have already lost most of their moisture content, resulting in a rain shadow effect.
- Ladakh, being located in the rain shadow region, experiences very little precipitation, making it a cold desert with arid and barren landscapes.
- The mountains of Ladakh, including the Zanskar Range and the Ladakh Range, block the incoming monsoon winds, preventing them from reaching the region and causing rainfall.
- The absence of rainfall and the high altitude of Ladakh contribute to its extreme cold and dry climate.
- Despite the lack of rainfall, Ladakh does receive some precipitation in the form of snow during the winter months, which is vital for sustaining its fragile ecosystem and supporting agriculture and livestock.
