Important questions based on NCERT syllabus for Chapter 7 - Weather, Climate and Adaptations of Animals to Climate:
Question-1: Prieto and his friends decided to go to Assam during their summer vacation but Prieto’s dad said that it will be too hot there during summer. Why do you think his dad said that?
Solution: Assam is a tropical region. The tropical region generally has a hot climate because of its location around the equator. Much more sunshine is absorbed to heat the earth at the equator. Even in the coldest month, the temperature is generally higher than about 15°C. During hot summers, the temperature may cross 40°C. Days and nights are almost equal in length throughout the year.
Question-2: What is camouflage? Why is it important for animals? Give an example.
Solution: Camouflage is the built-in protection in the animals which increases their chances of survival by tricking predators. Many tropical animals have sensitive hearing, sharp eyesight, thick skin and a skin colour which helps them to camouflage by blending with the surroundings. This helps them to protect themselves from predators. Example, big cats likelions and tigers have thick skin and sensitive hearing.
Question-3: Write the important characteristics of tropical rain forests? Which types of animals are inhabitants of this area?
Solution: Tropical rainforests lie between the Tropic of Cancer and the Tropic of Capricorn, or 1,400 miles north and south of the Equator. This region receives rainfall distributed regularly throughout the year, about 6-33 feet a year. It remains frost free and warm all year long, with temperatures between 70° and 85°F with very little daily fluctuation. Tropical rainforests are found in Western Ghats and Assam in India, Southeast Asia, Central America and Central Africa. Because of continuous warmth and rain, this region supports wide variety of plants and animals. The major types of animals living in the rainforests are monkeys, apes, gorillas, lions, tigers, elephants, leopards, lizards, snakes, birds and insects.
