Important NCERT Questions Class 7 Science Chapter 7
When are the maximum and minimum temperatures likely to occur during the day?
The maximum temperature of the day occurs generally in the afternoon while the minimum temperature occurs generally in the early morning.
Fill in the blank: The average weather taken over a long time is called ___________.
The average weather taken over a long time is called climate of the place.
The tropical rainforest has a large population of animals. Explain why it is so.
In tropical rainforest days and nights are almost equal in length throughout the year. The temperature of these region varies from 15°C to 40°C during the year. These regions get plenty of rainfall. Because of continuous warmth and rain, this region supports wide variety of plants and animals. The climatic conditions in rainforests are highly suitable for supporting an enormous number and a variety of animals. That is why the tropical rainforest has a large population of animals.
Explain, with examples, why we find animals of certain kind living in particular climatic conditions.
Animals are adapted to the conditions in which they live. These adaptations are the just because of long process of evolution. It would be difficult for them to survive if they are moved to region having different climate conditions than from their habitat. Consider the following examples: A polar bear has thick layer of fat under their skin which acts heat insulator. It protects the bear from extreme cold climate of polar region. The polar bear cannot survive if it is moved to hot and dry desert region. Monkeys have long tails for grasping branches adapted to live in tropical rain forests. It cannot survive in Polar Regions.
