Answer 1

Answer:

Answer: Two methods to find out wind direction at a given place are (i) An instrument called anemometer can be used to find the direction and speed of the wind. (ii) Hold a strip of paper outside. The direction in which the paper is blowing, is the direction in which the wind blows.

Answer 2

Answer:

The following are the two methods to find out the direction of wind.

(i) While flying a kite, air exerts pressure on the kite due to which the kite flies. The direction in which the kite flies is the direction of blowing of wind.

(ii) While riding a bicycle, the direction in which it is difficult to ride is opposite to the direction of the blowing wind.

Therefore, while flying a kite or riding a bicycle, the wind direction at a given place can be determined.
