How do animals like yak survive in the cold climate of Sikkim?
Yaks survive in the cold climate of Sikkim through several adaptations: (1) They have thick, long fur that provides insulation against extreme cold, (2) Their body structure is strong and suited for walking on steep, rocky mountain slopes, (3) They have large lungs to breathe in thin mountain air at high altitudes, (4) They store fat in their bodies for energy during harsh winters, (5) They are domesticated and used by locals for transportation and carrying loads in mountain terrain.
Explanation
The chapter mentions that Nayan enjoyed a yak ride in Sikkim and that yaks are commonly used there for mountain travel. Yaks are well-adapted to cold mountain climates with their thick fur and strong bodies, making them ideal for transportation in the Himalayan region.
