उत्तर १
The following are the two methods to find out the direction of wind.
1) 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.
2) 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.
उत्तर २
1) Take a piece of a paper in your hand. Allow it to fall from your hand. It will flow in the direction in which wind is blowing.
2) You can also use a wind-pane which helps us to know accurate wind direction.
