Picture Study

A. Observe the given picture and answer the following questions.

1. Name the given structure shown in the picture. 

Ans: It is a wind turbine

2. Which energy does it use? 

Ans: It uses wind energy

3. Is it renewable or non-renewable energy? How can you say so? 

Ans: It is a renewable energy as wind is a renewable source of energy .i.e. It will not exhaust with continuous use.

4. Is this structure beneficial for us? Write its role. 

Ans: Yes, it is useful because it converts wind energy to electrical energy which can be used and it is  a renewable source of energy.

B. Look at the given picture and answer the following questions.
