Question & Answer
Q.1: Fill the missing word in the blank spaces in the following statements:
(a) Wind is__________air.
(b) Winds are generated due to__________heating on the earth.
(c) Near the earth’s surface __________air rises up whereas ___________ air comes down.
(d) Air moves from a region of __________ pressure to a region of__________pressure.
Ans : (a) Wind is moving air. (b) Winds are generated due to uneven heating on the earth. (c) Near the earth's surface warm air rises up whereas cold air comes down. (d) Air moves from a region of high pressure to a region of low pressure.
Q.2: Suggest two methods to find out wind direction at a given place.
Ans : 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.
Q.3: State two experiences that made you think that air exerts pressure (other than those given in the text).
Ans : We have experienced that when we blow a balloon, the balloon becomes tight. If we try to fill more air, then the balloon will burst after an extent. This happens because air exerts pressure. We have also experienced the movement of fringes of windows and doors of our houses when wind blows in a high speed. This also happens because air exerts pressure.
Q.4: You want to buy a house. Would you like to buy a house having windows but no ventilators? Explain your answer.
Ans : A house having windows but no ventilators should not be bought. This is because warm air is lighter than cold air and therefore, it goes up. This warm air can go outside the house mostly through ventilators. If there are no ventilators, then the warm air cannot go outside easily.
Q.5: Explain why holes are made in hanging banners and hoardings.
Ans : Air exerts pressure. Wind blowing in high speed may break or displace many things. If holes are made in hanging banners and hoardings, then air can pass through these holes, which reduces the air pressure exerted on the banners and hoardings. That is why holes are made in hanging banners and hoardings.
