Describe the trees found in the mountains.
Trees found in mountains include oak, pine, walnut, and chestnut. These trees are adapted to cold climates and grow on steep slopes. Pine trees have needle-like leaves that help them survive in cold conditions. Oak, walnut, and chestnut trees are deciduous trees that shed leaves in winter. These trees are different from desert plants (cactus, khejri) and coastal plants (coconut, palm) because they grow in cold, rocky terrain with snow-covered peaks.
Explanation
The chapter mentions that in Sikkim's mountains, trees like oak, pine, walnut, and chestnut are found. Mountains are rocky landforms that rise high above the ground and are usually cold. Many Himalayan mountains are covered in snow. The trees are adapted to this cold climate.
