Short Answer Questions

14. Match the animals mentioned in Column I with their characteristic features given in Column II.

Ans: The correct table is,

15. Why is it difficult to predict the weather of a place while it is easy to predict its climate? 

Ans: The weather is a daily report of the atmosphere at a certain location in terms of physical quantities such as pressure, temperature, and humidity. After a short period of time, the weather in any given location changes. As a result, predicting the weather in a certain location is difficult. Climate refers to the average weather in a certain place over a lengthy period of time. As a result, predicting the climate of any location is simple.
