EVERYDAY SCIENCE

Detailed explanation-1: -Animals have many adaptations to survive in this harsh environment; Animals need shelter and insulation in the Tundra. The animals here tend to have thicker and warmer feathers and fur. Many of them have larger bodies and shorter arms, legs and tails which helps them retain their heat better and prevent heat loss.

Detailed explanation-2: -When the weather starts to get cold migrating animals fly or swim to a warmer place where they can find food. Animals that adapt to the cold weather often change their appearance. They grow warmer fur or feathers and sometimes change colour. Some animals change colour to camouflage themselves against the snow.

Detailed explanation-3: -An inactive state resembling deep sleep in certain animals living in cold climates to survive the winter is called hibernation. During hibernation, the body temperature of animals lowers and the breathing and heart rate slows down.

Detailed explanation-4: -The mountains have very low temperatures, sometimes below 0degrees. Therefore animals in the mountains are adapted to live in extremely cold weather. Their body is covered with thick fur to protect them from the cold. They also have a thick layer of fat under the skin for insulation and protection from cold.
